I'm wondering what a good upgrade would be for the Legacy chassis.

Questions:
1. are they a direct bolt on?
2. are there any mods/other parts then just calipers/rotors to be done (brake line, hub, anything else)
3. what is the going rate for a set of used calipers? (new rotors are cheap enough, but would like OEM calipers)
4. will I need bigger then 16" wheels (I still have the stock Snowflakes)
5. do I need to do front and rear at the same time, or can I just start with the front's?
6. what years will interchange and not interchange?

I know tons about Nissan brakes and what can and cant be done, but I'm not so up on Subaru's at this time, I'm working on it though... Any feed back would be great! :grin:

All price estimates are in Canadian...
All info is being doubled check so please double check my info before you make a big purchase/mistake

Unless specified this information is generic and applies to almost every subaru impreza/legacy/forester.

General:
a) (BBK) Big brake kit's on a 165bhp car is overkill but not dangerous ...
b) It is always recommend to go with stainless steel brake lines.. but you can re-use your stock brake lines for most conversions.
c) Running performance brake fluid is an upgrade on its own :-D
d) Running performance pads makes your setup feel like night/day. EBC/Hawk/Etc.. the more advanced the pad the louder/squeakier it gets..
e) You can just do the front upgrade but your brake bias will be off if you go with a over-sized front caliper.
f) You can keep your stock brake booster in almost every swap.

If you have 1-POT front Brakes and/or rear drums

1) Base models have 1-piston fronts / drums in the rear
-Brighton / Brighton SE /, OBS, (I am sure the OBS has drums but not sure about the 1-pots)

Brake lines:
---> You can use the standard subaru style stainless steel brake lines.
---> Regardless of f= 1 pot / r= drums or f=1 pot / r= 1 pot they still use the same lines

Front caliper upgrade:
---> 2 pot caliper + bracket + rotor from the majority of 2-pot subarus (LGT / Outback / SUS / WRX)
---> Same upgrades described in the 4-pot explanations below.

Rear disc conversion:
---> You will need the rear hubs/spindle from any disc equipped subaru as well as caliper/rotor/bracket/ebrake shoes/springs
---> New ebrake cables from a disc equipped subaru

If you have 2-POT front brakes

2) The majority of Subaru's use 2-piston fronts and 1-piston rears:
-LSi, GT, L SE's, Legacy Outback, 02-05 WRX, 2.5RS etc..
---> If you have front 2 pots and rear 1 pots then all the info below is for you.

OEM brake upgrades.

---[] Fronts []-------------------------------------------------------------------------------------------

Calipers
JDM GC STi (FHI) 4-pistons / 06-07 WRX are direct bolt on.
--> you need at least 16x7" +48/+53 offset rim to clear the brakes..
--> +53 offset 98-01' 2.5RS 5/6-spokes are cheap and fit the bill (thanks mike)
--> 06' WRX pads/rotors are needed
--> OR If you want to keep your GT/WRX rims 16x6.5 + 5mm Spacer = 16x7 :smt009


JDM GC STi v.3-6 (FHI)

http://img35.imageshack.us/img35/8004/gcstibrakes.jpg
--> These calipers came in black and red. and have embossed letters.
--> Not sure exactly how to narrow the model down..
Cost) Average cost of a JDM FHI f/r kit will go from Fronts $350-700 Rears: $250-600 for just the calipers..
If your lucky you can score the rear hubs..

06-07 WRX

--> These calipers came in red. and have a sticker for the letters.
--> You can use 3mm spacers to fit the GD 03-06 16x6.5 5-spoke OBS
Cost) 06-07' WRX setup will cost more since they are much newer.

-----------------------------------------------------------------------------------------------------------------

USDM 04+ GD STi Brembo's & JDM 01+ GD STi (internet calls these v7.v8.v9.v10)
USDM 04' STi / JDM 01+ STi Brembo 4-piston up front are direct bolt on to your stock hub!!.
--> If you purchased your Brembos with the front hubs you CAN use them if they are 5x100. Legacy Axle will slide in.
--> You need much bigger rims to clear these brakes... 17x7.5" I believe..
--> 04' STi pads/ 13" rotors are needed.

http://img8.imageshack.us/img8/3775/img2773ov.jpg - http://img151.imageshack.us/img151/6554/dsc01705v.jpg
Stock 2-Pot vs Brembo 4-pot
Cost) $1000-1500 depending on condition.
--> Usually you can get calipers, hubs, control arms, sway bars for $1200 at a JDM importer.

---[] Rears []--------------------------------------------------------------------------------------------

3 Methods for FHI 2-Pots:
i) JDM STi v.5/6 backing plates or USDM 06-07 WRX backing plates.
---> Perfect for people who want to replace their wheel bearings while they are at it.

ii) Caliper Brackets
---> Perfect for the cheapish/lazy man.. some grinding of the backing plate may be required.

iii) JDM STi v.5/6 Hubs w/ backing plates or USDM 06-07 WRX Hubs w/ backing plates.
---> Perfect for the ultra lazy man who just wants to PLUG-N-Play..
---> BC/BF/BJ & BD/BK/BG only. Multi-link rear BE/BH/BT & BL/BP are different.

Adapters/Brackets 2-pot Rears
JDM GC STi v.4-6 (FHI) / 06-07 WRX 2-pistons in the back need either:
--> Kartboy/Godspeed/Etc.. Adapters/Brackets
--> OR
-->5x100 JDM GC Sti v.4/5 rear hubs that had the 2-piston setup from a JDM wrecker.. No adapter just direct bolt on.
----> Legacy stock rear axles will bolt up to JDM STi hub.. even if the car came with LSD.. no difference.. splines are the same.
--> You can source 06' WRX rear calipers they are the same as the GC STi just red and fresher.
----> Same deal with the adapter / hub.. source the hub from a 06' WRX but it will cost more then the JDM version.

NOTE:
00-04 BE/BH & 05-09 BL/BP owners who want the Brembo 2-pot rears will have to chop/drill/snip off your factory dust/splash shields; they're too small. Also, the rear spindle will have to be clearanced using a dremel or other grinding tool to make room for the caliper bolts.

OR

--> BE/BH / BL/BP / and so on can not use non-multi-link hubs! No go!

2) -04' STi 5x100 Hubs (Expensive Conversion)
--> DOES NOT APPLY TO BE/BH - BL/BP and so on
--> You will need STi hubs, 12.5" STi rotors, pads, axles, R180 rear diff.
--> R180 comes from USDM 04-05' @ 3.90 (USDM 06+ @ 3.54 w/ 1:1.1 so no go)
--> JDM R180 comes from v.4/5 Type-RA @ 4.44 (they do not carry the abs hole for the sensor and the phonic ring for the abs signal-

--> There is a 5mm overhang because the tabs are just slightly longer vs. the FHI version.
--> The wrx/lgt rear rotors will work with either caliper, you need a vented rear rotor, as opposed to the non-vented version found on the "H6" upgrade (same diameter though).
--> Some have speculated using Toyota Celica GT4 rear rotors (turbo awd version, hard to find here in the US) to reduce the pad overhang, but finding rotors for those here can be very difficult.

If you can find a brake kit for either GC or GD style you have to abide by the rules of upgrade listed above.
-so many companies to list....

Damn! That was a lot to take in...

I do have some auto X quality pads front and rear right now and the difference was crazy! I dont remember the brand, but it was one of my race car building friends that set me up with them...

I can source new 02-04 WRX calipers new for about $80-90 aftermarket with rotors being $30 each...

This might be a dumb question, but can I use wheel spacers to get the clearance I need? Or is that just a bad idea? I would like some 07 Legacy 5 spokes (not sure of the size), but I do like the Snowflakes...

I know I have more I want to know now, but I need to read up and get this to all sink in...

12-23-2010, 09:46 PM
as I said before only 06+ wrx have the 4-pistons.. 02-05 wrx use the same 2-pots as the legacy.

You can probably get away with spacers.. I have a friend used 12mm spacer to clear the Brembo fronts ... its all about the offset and/or width of the rim.

Personally I don't like the idea of a spacer its just another item to break or cause issues but that's me.

Heres your good cheap upgrade that is bolt on:

Front loaded calipers for 2004 legacy gt plus rotors
Rear loaded calipers for 2004 legacy gt plus rotors

This will give you a much larger rotor surface including the H6 rear upgrade. Cost is around $180 for fronts and $220 for rears.

Will take you about an hour to do.

Sorry... its been years of info in my head and random pieces of recent info.. recently SLi is getting more organized so I though I can just throw all i got at this thread.. I think I am on revision #20 :-p

I wouldn't worry to much if your going with the FHI's.. look at the breakdown above you can see that v.3 STi's/ v.4 WRX came with 4-pot / 1-pot.

If your going to slap a 4-pot Brembo and leave your stock 1-pot in the rear it will definitely add strange characteristics to your car.

the 04-lgt upgrade the huffer listed is basically the 11.5" wrx front brake and 11.5" H6 brake upgrade.

You forgot to list the 05-07 Legacy GT brakes, its a massive 12.3" front rotor (for comparison the STI brembos are around 12.5") and dual piston caliper (need 17" wheels, any offset, because of the height of the caliper), and 11.5" VENTED rear rotor and single piston caliper (same rotor as FHI 2 pots). You need both calipers and rotors for this upgrade, and they bolt straight up. Dubbed the "best bang for the buck track setup" on NASIOC.

Most importantly, someone looking into brake upgrades needs to know what kind and size of brakes they already have. I've seen people buy a brake upgrade that turned out to be the same exact brakes that they already have on their car!

Good job Chuck!

Almost, it's the R32 GTR V SPEC and the R33 GTR that had Brembos. The two you mention had Sumitomo 4-pots. Also, your R32 GTR has 296x32mm front rotors while the R33 GTS-T has 296x30mm rotors. Will they interchange? Probably, but with the same danger as running rotors at or below their minimum thickness, or running pads that are always dragging till the pads loose ~2mm of thickness.

the R32 GTR non v spec had Brembos that they used on the R33 GTS-t. The R33 and R34 GTR's got the Bigger Brembos. R32 GTR v spec had very large Brembo brakes, since it only was out for the last 2 year of the R32 production 93-94. i do not know where you are getting you thicknesses from, but from EBC UK say they are the same part number. http://www.ebcbrakes.com/Assets/EBC_201 ... alogue.pdf (http://www.ebcbrakes.com/Assets/EBC_2010_Disc_&_Drum_Catalogue.pdf) look at link pg 161-162

as for the backing plates not working, i said 3rd gen. i would think 3rd gen on a legacy forum would mean 00-04 Subaru Legacy(Silly Marine). also you can go to my members ride thread to see the brake swap. VERIII Sti front 4 pots 06 WRX 2pots.

EBC part number GD699(Rear)is for the Nissan 2 pots calipers 1991-1996 Nissan 300zx turbo / 89-94 R32 GTR 2.6 Twin Turbo(non V spec) / 93-98 R33 GTS 2.5 Turbo / 97-2002 R34 GTR GTT these are not all the cars that these rear rotors would fit, but that is what i know they will fit.

also EBC GD695 will work with the nissan front 4 pots, just have to re drill the rotor bolt pattern.

^ i thought only the first couple years of 300zx 4 pots were aluminum, then they switched to steel for later years...

Edit...
"The following is a comparison of some different Z32 300ZX brake calipers.

The "26mm Aluminum" calipers were used ONLY on 1990 non-turbos. They used a 280mm x 26mm rotor.

The "30mm Aluminum" calipers were used on 1990 Twin-turbos and ALL 1991-1992.5 300ZX's (both turbo and non-turbo alike). They used a 280mm x 30mm rotor.

The "30mm Iron" calipers were used on ALL 1992.5-1996 300ZX's (both turbo and non-turbo alike). They also used the 280mm x 30mm rotor.

Of course, the easiest way to tell aluminum from iron is to use a magnet, but I hope this helps some people trying to figure out what they've got/are getting if buying with just a picture for info."

Also, this may be useful for anybody wanting to make an adapter bracket, that doesn't have any machine shop connections... still haven't had a project where i needed to use them, but i hope to give them a shot in the future, pretty interesting setup IMO.

04 sti brembos are the same calipers as R32 GTR brembos and R33 GTS t calipers. You will run into the mount dog ear difference like Ben has.
Good job Chuck!

The GTS-T part of that is incorrect. No R32, R33, or R34 GTS or GTS-T came from the factory with Brembo brake calipers. I believe they were all Sumitomo's, similar to the Z32 300zx brakes.



the R32 GTR non v spec had Brembos that they used on the R33 GTS-t. The R33 and R34 GTR's got the Bigger Brembos. R32 GTR v spec had very large Brembo brakes, since it only was out for the last 2 year of the R32 production 93-94.

don't try and school me on my Nissan's. Thank you.

The R32 GTR non-Vspec did not have Brembo calipers from the factory. Only the R32 GTR VSpec and VSpec II had factory brembo calipers. The R32 Vspec/Vspec II + R33 GTR + R34 GTR brembo calipers are all the same, except the R34 are gold.

2005+ LGT's have 1 pot ventilated rears, but you're right in that they are the same diameter as the H6's. Also, I don't think it'll work since the hub's are designed to work with the newer multilink rear suspension. So if you have an 1990-1999 Legacy I'd recommend hitting up the wreckers (as opposed to Pull-a-parts and the like) since they have better selection. Worst comes to worst there's online wreckers such as http://car-part.com/

the BE/BH hubs should fit the JDM hubs or 06' hubs. If you choose the STi hubs then you need to follow the info above.

As far as I know GC brake lines work on GD brakes. So I doubt there is any differences with the banjo-bolt style brake lines on the BE/BH.

You should read the entire thread again to fully understand what is needed and what is possible.

Your car has:
Brakes Power assisted anti-lock, 4 channel with EBD (elec. brake force distribution),
11.5 vented front disc
10.6 solid rear disc

You have 17" wheels, so yes you could fit the 4 piston/2 piston brakes on your car. Not really worth it though because your car still weighs about the same as the 00-04 Legacy, and has just 5 more HP on the engine.

backstory ... So I have a BD 2.5GT (daily driver for the mrs.) that has been on the backburner for a long time, give or take 10 years. Around 3 or 4 years ago I bought GR-2s with whiteline springs and end links. I finally installed the struts a week ago. I am excited about the sube again. The long term plan was a '04 STi swap, somehow I had it in my head that as the donor cars aged the price would become affordable. But something happend ... the popularity of swaps has exploded and I dare say increased the cost (damn VW, porsche, & sandrail guys) ... and my car got old which forces me to question the practicallity of a $8-10k investment in a 14 year old chassis. To make matters worse I start to worry that the number of guys messing with BD legacys has probably decreased from a few to even fewer. Also, with stock turbo LGT's, spec b's, and 3.0Rs rolling around would a sleeper BD really be cool anymore. Would I actually be smarter to by a STi or LGT? Had I let my dream die when I wasnt looking?!

Enter Chuck and Huffer .... the dream is alive!

Huffer I totally agree with your message here;


^^^ all good info Chuck, but maybe preface the thread with something like "figure out WHY you need a bigger (size) brake system, keeping in mind that bigger systems are not always better depending on your application". I hate seeing people put massive brakes and end up complaining that their 60-0mph time is worse...because they just added a whole bunch of unsprung weight.

One of the things the older chassis have going for them is potentially reduced weight. Watching everything car bloat up lately fills me with flashbacks of the mid 70's. Thankfully I doubt we will see big blocks with under 200 hp again but 4000 lb cars with 400 hp are also a step in the wrong direction. It is a cruel irony that many mods although cool actually decrease performance due to added weight (brakes and/or drivetrain).

So are weights available for the upgrades above?

What is the penalty for each step?

Is the LGT setup the sweet spot for cost and weight are minimized, and performance is maximized when compared to the alternatives?


I am also trying to pull together a similar camparison for popular engine swaps EJ207, EJ255, EJ257, EZ30, EG33, EZ36. For some reason it is really hard to get consistent numbers I will post what I find on SLi. The goal is to minimize weight, and cost at a torque level agreeable to the 5MT.

Huffer
12-07-2011, 10:23 AM
Unfortunately I don't have weights - there are a lot of variables depending on if you use stock pads, rotors and not just the calipers.

Put it this way - the 04 LGT FRONT brakes are heavy, but they have better cooling vanes in them to allow heat to dissipate faster. They are marginally heavier than the 1998 GT Front brakes.
The rears are on the 04 LGT are significantly heavier buy a few pounds because the rotor size is nearly an inch larger. Keep in mind though, that neither upgrade is "necessary".

For the lightest factory brakes, a set of STi Brembos is the only place you can go without doing crazy fabrications or going to a brake manufacturer like Stop Tech for their "BBK" hardware.

The greatest weight saving on a brake system is in this order:
Caliper + bracket
Rotor
Pads

You could easily swap in a Forester XT/Legacy GT or WRX engine and keep the same size brakes on your BD - just upgrade your pads and spend the money on grippy tires.

great advice.

agree 100%, I have never had a complaint with the BD brakes. I have no plans to race the car, I just want to be able to pass on single lane highways with confidence. The car is torquey around town but falls on its face once I move into the oncoming lane! What I would love to do is take some serious weight out of the car ... then I need less HP and smaller brakes.

That said the brakes are 14 years old when the time comes to rebuild/replace I imagine that the cost to upgrade will be negligable so it is great information to have.

Also if I stumble across a engine donor car it helps to know what brakes on on what because I may decide to take the brakes as well.

I wonder if there is a bracket to use brembo's with smaller vented rotors?

12-07-2011, 12:29 PM
I've been asked this question over and over through Private Messages.

If your not looking for incrediable braking and have no plans for track duty then a simple combination of:
- EBC/Hawk Pads
- Generic Vented Rotors
- Stainless Steel brake lines

The pads on their own will yield fantastic 60-0 times :-D

If the calipers are an issue for use vs age then a simple trip to your local aftermarket parts depot will happily have rebuilt calipers in stock or you can source 02+ 2.5RS/WRX brakes.. Same jazz as the BD's 2-piston brakes :-D

I'll see if i can find caliper & rotor weight. I doubt pad weight is a concern.

Thanks Chuck.

I am not worried about pad weight. The rotor and caliper weights would be great info.

If an option existed to reduce unsprung weight while maintaining equivalent braking performance I would consider that a great "upgrade".

Huffer
12-07-2011, 03:59 PM
^^ you could always use used rotors. They'll have been turned to be thinner, but still within safety spec.

Not really worth the risk. Other alternatives would be the 2 piece type rotors - they have a lot less mass and are used for racing applications mainly. At some point you reach a critical juncture between cost vs. actual results produced.

Can you revised the H6 upgrade to where you need the whole caliper out of 2000-2004 legacy (probably more) because the cardone/h6 bracket won't work with the older phase 1 rear caliper. The phase 1 calipers uses 1 bolt and a stud and its bolted to the bracket. While the H6 upgrade uses slide pins.

https://sl-i.net/FORUM/images/imported/2011/12/bracket-1.jpg

chuckthefuk
12-14-2011, 12:39 AM
So from your post it seems that the

1) 95-99 Phase 1 rear 1-pot caliper is not compatible with the H6 bracket.
Solution --> Upgrade to 00-04 Legacy Phase 2 rear 1-pot calipers

2) Based on the H6 caliper p/n = 26625AE000 and a cross-reference search @ opposed forces it shows that the same p/n is used on all 00-04 Legacy / L-Outback H4-H6 / Baja

3) So does this mean that the BE/BH guys don't need the bracket and can go directly to the rotors?

4) And does this now mean this upgrade needs new pads? I am also confused as to how the GD impreza calipers work with this bracket? Considering the caliper itself is only used on the BE/BH chassis p/n = 26692AE000.

r3v_v3ng3
12-14-2011, 01:08 AM
1) Correct, Phase 1 needs the whole caliper w/bracket from 00-04 legacy phase 2 rear 1 pot calipers

2) Yup. This upgrade is more for the bd/bk (dunno about the previous legacy) since the 00-04 legacy/outback/baja comes with it stock

3) No, I believe BE/BH already come with it stock already

4) Basically buy everything off a 00-04 legacy (rear calipers w/brackets, rotors, pads and clips). The phase 1 impreza's also have the same rear calipers as the bd/bk (1 bolt). Phase 2 (99 and up) started to have the 2 slide pins so it will work with the H6 bracket.

bump for WRX/2.5RS caliper / bracket info?

r3v_v3ng3
12-15-2011, 01:32 AM
I can't find any info on the wrx/2.5rs rear brackets but this list the sizes of the rear rotor and the rear pad numbers

Rear Brakes

266x10mm
The most common Subaru rear rotor. It uses a single piston sliding caliper, of which there are a few variations. Early Legacy sedans (non-turbo) and Imprezas have a smaller piston than Legacy wagons and turbos, and there are a few bracket/caliper revisions.
Applications:
90-99 Legacies/Outbacks with rear discs non-turbo
93-07 Imprezas with rear discs (except sti, 06-07 wrx)
98-08 Foresters with rear discs
Bajas

274x10mm
This rotor is on most 05-09 Legacy/Outbacks. The exception is the LGT and probably the 3.0R. Parking brake is 170mm. Seems to be only be on these models.

286x10mm
2008+ impreza/wrx
2009+ forester (with rear discs)
2010+ Legacy 2.5i
uses a 190mm parking brake and 1-pot sliding calipers.

290x10mm
This is well known as the H6 rear rotor. The Legacy caliper is the same as most other 99-07 1-pot Subaru calipers so you can upsize to this rotor simply by purchasing the brackets and correct pads
Applications:
00-04 Legacy/Outback non-brighton
SVX (5x114.3)

Bonus points: SVX bracket + this rotor in 5x100 = old style caliper H6 upgrade (probably).

266x18mm
This is the Legacy turbo rear rotor. The caliper is similar to the other calipers but is wider to accomodate the vented rotors. I hear it was also found on the v1 WRX (93-94).
Applications
91-94 Legacy turbo

290x18mm (170mm parking brake)
290x18mm (190mm parking brake)
290x18mm (2010+ Legacy GT)
This is a new rotor size for Subaru (in the US anyway). It uses either a 2-piston opposed caliper or a 1-pot slider. The 2-pot will not bolt up to other Subarus without something like the Kartboy brackets or having a new backing plate pressed onto the spindle. There are three versions of this rotor, one is for the regular 170mm parking brake, the others are for the sti 190mm parking brake in both 5x100 and 5x114.3
Applications:
05+ Legacy GT (1-pot)
06-07 WRX (2-pot)
SVX (5x114.3) (only in JDM-land)
Some older non-us spec-b Legacys and wrx/sti models (see rear brake redux)

Note: The LGT uses a different brake line than older Legacies and Imprezas. So I think you need to grind down part of the caliper where the line mounts to get it to work on an Impreza. The LGT lines are a different shape and mount and a different angle and you can't use them.

316x20mm (5x100)
316x20mm (5x100, 170mm parking brake)
316x20mm (5x114)
STi brembos. There are multiple versions of this disc. One for the 04 STi, one for 05-07, one for 08+ and one with a 170mm parking brake drum. There's an explanation how to install rear brembos on other cars a little farther down. 08+ sti rear rotors have a different backspacing.
Applications
04+ STi

320x18mm
Hey that's an odd size now isn't it. I was previously wrong with my thinking the Tribeca uses the same rotor as an STi. It does have the same bolt pattern (5x114.3) though. AFAIK, it uses a 170mm parking brake but don't quote me on that.

Some D-plate numbers
I should note that the caliper bracket, and not the caliper, is what determines pad shape. So while there are a few different pads, in some cases the calipers are the same.
Rear 1-pots

D471:
1990-1999 Legacy
1993-1998 Impreza
1993-1997 SVX

D770:
2000-2004 Legacy
2005-2009 Legacy GT
1999-2002 Impreza

D1004:
11/2002-2005 WRX

D1114:
2005+ Legacy 2.5i/Outback (incl 2010+)
2008-2011 Impreza
2008-2012 WRX
2009+ Forester

bump for WRX/2.5RS caliper / bracket info?

there are three different rear brake setups for the 266x10mm rear rotors. The early one that's pre-99, one that covers something like 00-04 depending on the model/year, and then a later 04-07 bracket. The 05+ non-gt legacy and 08+ impreza use a different size rotor and caliper setup that we don't really need to be concerned about because it's not any bigger or better than "H6" brakes.

The 90-99 setup uses that pin and bolt setup. You can probably do an H6 upgrade on these with an SVX caliper bracket but I haven't actually confirmed that.

The 99+ brakes are what's found on, for example, an 02 WRX. They use the same pads as the H6.

The 04+ brakes use the same actual caliper as an 00-04, but the bracket and pad are different. If you have an 04 wrx and want to do the H6 upgrade, you need to get the older pad style. On that note, if you want to upgrade your pre ~03 LGT or RS with the bigger WRX front brakes, you have to use an 02 WRX bracket because they don't interchange between the caliper styles.

As for the term "H6," ALL 00-04 Legacies have these brakes, regardless of whether they are an L, GT, H6, whatever.

I was very close to going with a nissan setup with subaru rotors. I planned to design and fabricate my own cnc "kartboy style" brackets (no bushings or spacers). As luck would have it, I found a JDM FHI 4/2 subaru setup for less money and much less work .... but still far more work and expense than a H6 rear upgrade for equivalent performance.

permanent picture links with a dedicated server.

You should use the forum attachment system, that way they get stored in the database right along with everything else. no more link rot with that.

New to the forum and was wondering if anyone could provide me with the part number for the brembo rear backing plates for a BE or BL? They are not listed on websites such as opposed forces or similar. They can be had trough Japanse auction sites, but at a very high cost.

Thanks !

There is a thread on here with part numbers for all of the S401 special parts, but the Brembo rear backing plates are restricted parts.. meaning, unless you can prove to Subaru that you own an S401, they will not sell it to you.

I do believe that an aftermarket company made a set, but they are exceedingly hard to find at this point.. You might as well do what I did, and source S401 rear brake assemblies, since many of the S401s are being parted out in Japan now-a-days.

thanks for the input, did not know subaru didn't want others to do a brake upgrade on a non s40X car...

there are 4 sets for sale: 2 on japanese auction sites, but the company I use for the shipping - fromjapan) doesn't want to ship them (since there can be traces of oil), and the other 2 sets are based in canada, and that seller wont accept visa or paypal :s

I will take this to PM so as to not get too off-topic here. :)

The other option is to just use the standard caliper bracket adapters and shave a bit off the spindle to clear the caliper as most do. This avoids changing wheel bearings in order to change the backing plate.
