So, I am trying to decide between two BBK's:

Stasis Alcon 355mm 4 piston or
Brembo 355 6 piston.

I can get both for almost the same price. It will be going on a B7 S4 behind OZ Superleggera 18" wheels.

Which one is best? Lightest? Best for street and very light track?

save you all the rotational weight for 1/3 the cost! You are never gonna track the car, so... why not?

I'd pick the one that results in a brake bias closest to 2.3:1.<ul><li><a href="http://pws.prserv.net/usinet.Young/BrakeBiasCalculator.html">Brake Bias Calculator</a></li></ul>

I guess I wont really be tracking the car all that often, but would this actually be an idea I should consider? They do make 15lb front rotors... That should help a bit with the unsprung weight, right?

Or should I just do a BBK? (Kinda feel like that is the right thing to do, but am still learning here...)

I just put an order in for some Aclons!!!

CAnt wait to get those beauties on my car!!!
