In Reply to: I disagree. Stock brakes were designed for a car that's factory limited to 143 mph. posted by Flyboy on 2006-05-02 18:09:00

brake horsepower can be measured, right ? A 400-500 hp, 3600 lb car needs all the brake horsepower it can get. If I had stock brakes on my S4 and went to the track, I'd be risking my life after one lap.

Stock S4 calipers are well built, but the rotors bow out very early when heated up.

You are giving out seriously bad advice here !!

A 500hp s4 will have significantly higher entry speeds at EVERY braking zone - nyet 2006-05-04 13:41:37 (65 views)

And it's braking zone will start sooner so it can slow to the speed of the other car. - Flyboy 2006-05-04 19:01:46 (66 views)

Braking points depend on tires and brakes, not horsepower. - zev@avalonmotorsports 2006-05-05 12:10:35 (54 views)

I agree - to a point - Shabadoo Tooning 2006-05-02 18:08:52 (69 views)

isnt the only function of bigger brakes to not fade during repeated heavy braking (at the track)? - mtaesch 2006-05-02 18:15:01 (56 views)

Yes. They're simply a larger heat sink for the energy to be dumped into. The - Flyboy 2006-05-02 18:29:31 (85 views)
