I'm still wondering what the connection is between the ability of a vehicles

brakes to stop the car, and the amount of horspower that the car produces? At the Audi DE's I've attended I saw a bunch of 2.7T S4's and B6 S4's, all pretty powerful cars in stock form. Is there a particular HP level where upgraded brakes are required? And if so, how is that level determined?

If you can, take it to the track in stock form so that you have a benchmark - O.W. Kenobi 2006-05-02 15:04:00 (66 views)

you will need brakes - Shabadoo Tooning 2006-05-02 14:42:21 (64 views)

Why will he 'need' brakes? The car comes with them. - Flyboy 2006-05-02 16:51:26 (59 views)

stock brakes are woefully inadequate for a stage III car, especially if he's going to the track - Shabadoo Tooning 2006-05-02 17:24:28 (64 views)

I disagree. Stock brakes were designed for a car that's factory limited to 143 mph. - Flyboy 2006-05-02 18:09:00 (106 views)

Sounds to me like you've never been in a tuned S4 before ! You do know that - zev@avalonmotorsports 2006-05-02 23:14:36 (140 views)

A 500hp s4 will have significantly higher entry speeds at EVERY braking zone - nyet 2006-05-04 13:41:37 (62 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 (64 views)

Braking points depend on tires and brakes, not horsepower. - zev@avalonmotorsports 2006-05-05 12:10:35 (52 views)

and its going to dump more energy into the brakes - nyet 2006-05-04 19:23:34 (51 views)

If you drive at all fast on a roadcourse, you're going to fade the stock brakes after a while. - O.W. Kenobi 2006-05-03 08:13:01 (64 views)

They'll be good for one stop from that speed. But that's about it... - O.W. Kenobi 2006-05-02 18:51:00 (56 views)

in my opinion, only if he is going to the track are they really needed - mtaesch 2006-05-02 18:03:22 (54 views)

I agree - to a point - Shabadoo Tooning 2006-05-02 18:08:52 (65 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 (55 views)

Yes. They're simply a larger heat sink for the energy to be dumped into. The - Flyboy 2006-05-02 18:29:31 (82 views)

If that car is being driven hard during those 1-2 track events, then yes, a BBK is necessary. - O.W. Kenobi 2006-05-03 08:14:58 (50 views)
