I just ordered 10 sets of custom E-brake shoes for the G8 and Camaro SS rotors.
I hope to have them in about 1-2 weeks time.
Just a heads up to everyone interested in keeping your ebrake with the rear brembo upgrade. I will also have all the other parts needed except for the bracket that Realsquash will be selling soon.
Post here if you are interested in a set.
