Sport Brake Rear Converstion Attempt #2. SUCCESSFUL.
Second attempt went much better. New Bolts, New Caliper.
This time they didnt have messed up threads so they went right on.
Centric high carbon blacks + Carbotech XP8 rears are good to go and are slowly bedding in.
(Side note: I have 2 base model sized rear rotors i bought because when the first install was a flop i needed rotors to make it back home. If interested they have ~650 miles on them and barely even worn in. Shoot a PM if intrested.)
