I'm trying to decide on a Big Brake Kit. I've got a chipped B5 S4 w/ Bilstein pss9 suspension. I'm leaning towards the Stoptech 332mm kit or the Porsche 993TT kit that ECS tuning sells. The car will see track time w/ club racing events. Any thoughts on a brake setup. I'm trying to order something ASAP...I haven't been able to locate anything used.

deal with them to get some rotors, I'll never deal with them again by choice. They were also bought out by Centric a couple years ago. Anyway, I would not trust the products from a shady company that does not operate professionally and bites other people's products, especially for components as important as brakes. The Porsche brakes should be re-badged Brembos and that's all good.

If you want something a little better, look into the Stasis (Alcon) setups and if you want something serious, Brembo GTR's or Alcon racing brake systems...

Have other people had bad luck w/ Stoptech? It seems that their dealer network is fine as far as supplying replacement rotors/hats,etc.

I'd also recommend going with a rear track pad too if you're using track pads up front.

Try Zeckhaussen racing, he usually has stuff in stock.

excellent to deal with. Personally i would highly recommend the stoptech product and their support group has been great!

I had pads on order from them as well that took two weeks to arrive (also supposed to arrive same day) and to make it all even better, they sent the wrong pads...

and balanced for the front engine S4? interesting...<ul><li><a href="http://www.stoptech.com/tech_info/wp_brakebiasandperformance.shtml">Brake bias w/ charts on Porsche setup vs Stoptech setup on S4</a></li></ul>

- Volume
- Engineering expertise
- Liability and experience

major manufacturers aren;'t as dumb as the aftermarket likes to suggest.

I dont mean to suggest Stoptech is not a quality outfit.

I am much happier with the stoptechs.

I read a white paper article that explained the research and design/engineering that goes behind porsche braking technology. More than just buying brembos and sticking them on there. I have a patient from Germany that is a retired engineer that worked for Porsche.

bigger pad, bigger pistons, different materials?

These engineers are brilliant!!!! Amazing knowledge and it proves there is so much we may not ever know about the testing, manufacturing, their software and engine tuning. Crazy technology and this guy is dripping with knowledge, makes me feel inadequate even with my Ph.D. in Health Technology.

Weight, swept area, f/r bias, etc. Porsche offers lots of brakes, even options on the same car. Bigger, drilled, plain, 4-p, 6-p, ceramic, iron, ... how thick's your wallet sir?

But mine are pretty standard issue brembos, with the P-logo, and they are VERY good. Make that amazingly good. but keep in mind that such firm, linear feel is a system design that extends fromt eh pedal, through the MC, through the biasing system to the calipers. brembo makes only the calipers, and the rotors.
