I'm going to be hopefully going up to Washington and buying a set of stock WRX brakes, brackets, calipers, rotors, and 2 complete sets of pads, front and rear, they're going on my BK (no longer have the BE).

I got my BE's brakes so hot that the rotors were glowing bright orange. That was driving down a 14 mile stretch of road, the start of which is at 5,600 feet, the bottom at about 3,500 feet. I now found an extended section of road, it goes another 15 miles, and is extremely twisty, and it finishes at about 1,800 feet.

Will WRX brakes be enough for me?! We're talking going from 55 to 35 mph on extreme downhill roads probably 40 times in the course of 20 minutes, and that's not even pushing it! Pushing it is going from 100+ to 35 multiple times, often with a steep, sheer drop, and no real guardrail, on the very edge of the road. Engine braking helps, but it's almost too easy to dump it in second and drop the clutch when going 80 mph, which would be bad for the engine in more than one way. Brakes are a must!

WRX brakes, front and rear, will cost me $280 ish, plus however much gas it takes me to drive from SoOrg to NoWash. Worth it, or should I get 17" in wheels and 4 pots? Or should I get ceramic rotors and pads? My BE had OEM rotors and ceramic composite pads which worked really well once the brakes warmed up, but once they started glowing, they faded really bad. The OEM pad material just freaking caught on fire, and smoked a lot, whithout really having any kind of grip on the rotor once the rotors got to "slight glow".

The last thing is, is there an easy way to change the brake bias on the fly? The second time I hauled butt down the mountain in my BE, the front brakes stopped working, more or less, and the only way I could slow down was pulling the parking brake lever about half way and leaving it there. losing brakes on this hill at 55 mph, or even at 35, could be fatal. At 35, with no ability to slow down, the car will accelerate, even just using engine braking.

I haven't got an answer to your question, but I do have a solution... Don't go speeding down a mountain and slam on the brakes expecting to stop right away :lol:

Aww, what's the fun in driving up mountains, then?

Maybe I should buy a go cart and make noise in my neighborhood all night long...

Your rear brakes are the same as the WRX in terms of rotor size IIRC.

WRX front brakes should be ok. Change to high temp brake fluid (like super blue or motul) and high-temp track pads if you're really worried about brake fade.

The last affordable step would be LGT front brakes (12.3 inch wide rotors and BIG dual piston calipers).

I've got a large gap between the caliper and wheel in both the front and rear? I though the WRX brakes wouldn't fit 15" wheels...

High temp fluid had been one of the things I did on my BE. The BK needs uber brakes, it weighs a little more than the BE. =\ I'm mostly looking to completely fill the 16" wheels (I've got 2003 WRX stockers), so should I get H6 rears and WRX fronts?

What kind of rubber are you rolling on, and consider an upgrade to your pads and fluid...you could probably fit some Brembo blank rotors too.

sounds like wrx fronts and H6 rears would fit your bill. Brembo blank rotors would probably do the trick. They are much higher quality and better vented than OEM rotors. You're a little off on your prices- front wrx calipers and brackets can be had for $70-120. For the H6 rear upgrade, you can either get only caliper brackets and run the solid, 290mm rotors with your stock calipers, or you can buy calipers and brackets for the 290mm vented rotors. The latter option is a good $400 for all three parts.

whatever you do, don't buy ebay special "drilled and slotted" rotors. They are all garbage unless you go for brand name, like Brembo, and then you have to make sure that they are not drilled/slotted as an afterthough by some company other than brembo. Blanks are probably your best bet and fairly cheap from vendors on nasioc.

I'm gonna be rolling on either Kumho KH11's or something similar. I had KH11's on my BE, and liked them a lot.

Alright, WRX fronts, H6 rears. I wouldn't ever use ebay rotors, regardless. :p If I ever did get drilled or slotted rotors, I'd get them designed that way. Drilling a rotor after it's been made reduces it's inherant stregnth. If anything, I'm tempted to get a set of slotted Brembo's from Tirerack along with a set of KH11's. I'd like to get the brackets, calipers, and pads before getting rotors. I'll replace my brake fluid again when I get the new calipers.

The $280 I was talking about was for WRX brackets, calipers, rotors, and two complete sets of pads, front and rear.

My stock calipers look like crap. they're rusting, and look, well, flimsy. I'd like to ditch them and get a set of new calipers.
