I don't know what the original poster really wants here.

Could you please explain the problem you percieve with your stock system?

1. Do your brakes fade too much on the track? (This will most likely NEVER be the case on most roads)

2. Do you have so little braking that you cannot outbrake your tires? (This means that in a solid braking situation you cannot invoke your ABS)

3. Do you think that your brakes don't have enough response? (This means you have trouble modulating your brakes)

For 1: Try better rotors; if you can find rotors that cool more efficently than the stock rotors, go for it. Also, get Motul 600, ATE or similar high performance fluid with a high boiling point.

For 2: First, try different pads. For road/light track cars I like Hawk HPS and Pagid Blues

For 3: Teflon coated stainless steel lines. (Night and Day difference in brake feel)

Okay, how do I know all of this? I've tracked a couple of cars (Miata/Z3 2.5i/NSX/Vette Z06) and driven thousands of back country miles in supercars.

The best brake feel I've ever experienced was with my NSX. The stock brakes were horrible (2 Piston single sided cast jobs with small rotors). Without changing calipers or rotor size, I achieved braking greatness by taking the steps above.

I don't know if you just want to spend money or if you want better brakes, but that's the way I'd go first.

If I knew where to get some good multi-piece rotors that fit the stock calipers for my new used '04 Boxster S, that'd be the first thing I'd do.
