Please post which BBK you have upgraded to and how happy you are with it on the track. I don't care how many pistons or how pretty it is, just performance (and price). If you have done a BBK and are disappointed in the performance please post that as well.
I am posting this in the track session specifically for feedback from those tracking their M3's.
Some upgrades I have being installed this week are track dedicated CCW c10 18x10 square rims with 275/35 Hoosier tires, Dinan springs and camber plates.
Stoptech BBK offers you the best bang for your buck in my opinion. You will have much broader brake pad selection, cheaper replacement pads and discs, and more caliper to wheel clearance(Stopetech's 6 piston caliper has a much lower profile than Brembos).
