SCCA Autocross: Need your car classed? RIGHT HERE

[deadlydave]

Hello again. This thread has one point and one point alone, SCCA autocross (Solo II) classification.

Link to SCCA Rulebook 08: http://www.scca.org/documents/Solo%2...lo_Rules_2.pdf

Post the following, and I will help you figure out where you belong:
Car Year
Car Make
Car Model

Engine Mods
Suspension Mods
Wheels/Tires
If you have removed any interior pieces

If you're anything like me, you modded your car and then decided to autocross. I got screwed because of my hood, for instance.

how about my 84 RX-7 that has a 5.0 Small Block, no other mods except for the fuel pump to make it run...
EMod right?

I'd say you might be in Street Mod 2. We have a swapped wagon that runs in my region as SM, but they have a ton more mods. Also, they have 5 seats instead of 2.

The engine isn't a Mazda engine, so he's going up from SM2. Either Emod (I think...) or a prepared class.

ground effect kits <- huh no lights on the bottom of your car?

[deadlydave]

No, the original meaning of 'ground effect kits' is 'body kits'. think front lip, side skirts, rear lip.

[ShadowGT]

Interesting. I was actually considering SCCA, I live fairly close to Houston and I know they do stuff there. Of course, I still need to get some mechanical issues resolved before I start flogging my car.

I wonder, I suppose with my intake system I fall in the street prepared division. But I'm curious if removing my hood scoop block plate is considered as a ram air induction because I'm not using the stock air box but a cold air intake.

But this endeavor will be awhile off. Still need to chase my ECU problems around.

[Grafton]

Those brakes are going to mess with your classing. Most local regions would probably let it slide and allow you to run in STS. You're technically in SM I believe since they aren't original calipers on your car. I would email your local region and see if they'll let you run in STS.

really the breakes giving the most trouble, i figured the sway bar would be the most trouble...

well looks like my integra will never be a competative auto crosser haha

Your brakes wouldn't be a problem if you had a GT to begin with. I know you can completely update your car to GT specs, but it has to be EVERYTHING, which is tons of work. Since the GT was offered with those brakes, your local region should let that slide, you'll just have to ask. I'm not sure on updating just one part, but I don't think it's allowed. Swaybars are a pretty common item in auto-x racing.

[Huffer]

Car Year Make Model: 1998 Subaru Legacy GT wagon AWD 2.5L
Engine Mods: Lightweight crank pulley, headers, catback exhaust, 96 GT factory intake, snorkusectomy.
Suspension Mods: lowering springs, KYB GR2 struts (OEM spec), 22mm RSB, front and rear strut braces, Hawk HPS pads (front)
Wheels/Tires: 16x7 205/55/16 Kumho Ecsta (OEM size and offset...for an Impreza RS)

Full interior, factory front seats swapped for 06 STI fronts, 02 WRX steering wheel w/ SRS airbag.
Short shifter

My guess is Street Prepared.

[Mr. Sociable]

EDIT:


Huffer -

You're completely fine in STS except for this rule:

D. Alternate steering wheels are allowed except that steering
wheels with an integral airbag may not be changed.

I'm not sure what "integral airbag" means, but if it means what I think it does then you're F-ed. I would say that as long as the airbag in the WRX wheel still works and it looks good you should be fine.

[Huffer]

Nice. yep the SRS airbag in the WRX wheel is the same as the one in the stock wheel. Should look very stock.

Other than having no idea what a neon coilpack or grounding straps are, you're in STS. I also know for a fact that if those provide no significant gains, the STS guys should be fine with letting you run locally here in CO.

[Plays_with_Toys]

Have you ran STS in colorado? If so, what's the competition like? As for the neon coil pack, it's simply that. A dodge neon coil pack rated at 34,000volts compared to the 28,000 volts stock on the legacy. It's just a step down from an MSD ignition coil at 35,000 volts. But no. No appreciable difference besides being slightly more peppy and alot more smooth. The grounding straps/grounding kit was a debated item for a while. SCCA never really clarified if it was a class changing mod. That was a year or 2 ago, wasn't sure if the ruling had been made yet.

[Mr. Sociable]

Then you'll be fine running in STS. I've never run in that class myself, I've met a guy named Mark who runs in a 2.2 Impreza and there's some dude in a newer 2.5i too. Otherwise, it's full of pretty damn well prepped civics mostly and it's a fast class. I know in X class there was a fast as f*ck STS civic too. If you're a decent driver, you'll do ok.

[evolegacy]

ok this has me curious about mine, so let me toss my 2 cents in and find out what class I would be part of.....

1998

Goodyear Eagle RS-A 205/55R16 91H

Interior
A-Pillar Gauge pod
Volt Gauge
EGT Gauge
AFR Gauge
3.5" Tachometer

OK thats what I have so far, if you could give me the classification for that setup that would be cool, if you want to classify what im about to post you can do that too. I am going to post the future mods that I plan for the car and hope to get done before the meet this year.

Engine
Hyper Ground Wire Kit
Nology Spark Plug Wires
Nology Spark Plugs
APEXi SAFC NEO

Surprisingly all of this is only going to run me a little over $6,500, but its because i want to keep this build strictly N/A, afterall, N/A is better than turbo HAHAHA.

[jey]

Header will put you into STS.

The proposed mods look allowed in STS except camshafts - I think that bumps you to a higher class.

[Mr. Sociable]

^ Bingo. I'd look into the spring/retainer kit as well.


Otherwise it looks like a well sorted STS car suspension wise.

[evolegacy]

ya im going to add that kit in along with the cams when i get around to picking them up

[Mr. Sociable]

ya im going to add that kit in along with the cams when i get around to picking them up

I meant that the kit (as well as the cams) will bump you up into either FSP or SM. I don't know which.


I would skip on the cams/kit and do everything else. You'd have a great local STS car.

Oh God, if at all possible stay out of SM. I'll go back through the rulebook tonight, is the 09 one out yet? FSP probably wouldn't be too bad. I know locally, there are almost no protests and we kind of 'trust you' to help us class you. If you are slow or hit a lot of cones, nobody will protest anyway. :smt002

[evolegacy]

lol ok so you think i should skip the cams then? hm...well, it is pricey, main reason i was getting them was for added HP for the drag.

[deadlydave]

Ultimately it's about what you want to do with the car. If you want more power, totally go for it and have fun at autocross. If you want to win or trophy in a class, you have to mod a car to the maximum allowable for a class, and SM is very expensive. So, if you're just doing it for fun, to push your car, I say mod the crap out of your car and class be damned. If you're a competitive person and really want to do well, then you might wanna mod towards a particular class.

[Brockley]

I run XP now... lol

[2.5GT]

I would also like to know where I fit in
