I just purchased a used M2 BBK. It is the Wilwood SL6 caliper one with the 13" er 12.7" by my ruler rotors. Anyway...

For those that actually have this kit and go to the track with it what rear brake setup are you going with to get close to stock bias.

The options I have been thinking are this:

It is pretty trivial to fab up a bracket for the rear brake caliper to make it fit on a 12.7x.8 rotor. Im just not sure that is going to result in good balance.

I could just go with the 99-spec rotors (12.36x.8) and fab up a bracket.

I could use either one of the aformentioned rotors and put a wilwood 4-piston NDL like Maxcooper.
