How to?? CTSV Brembo 4-piston REAR brake swap for fourth gen
Hi i tired looking but wasn't able to find any solid info.... I want to know if anyone has done it, if so how and what parts did you use?
I know you need the brackets , if so which one and who do you recommend?
Thanks for the help in advance

There is little to no info because its not a functional mod, if anything its dangerous. The stock rear brakes + good brake pads are enough to lock up the rear and can cause brake hop or worst case scenario cause you to lock them and spin out. Adding more rear brake power will only make this worse and not actually help the car stop at all. You have to remember these are solid axle 3-link rear suspension cars with 55/45 weight balance, not 50/50 weight balance sports cars/sedans with multi-link IRS, so what works on a CTS or corvette does NOT work on these.

With a proportioning valve, you can run whatever you want.
With that being said, the bigger issue is c-clip axles and fixed piston calipers. You'd need to either convert to a bolt in axle or move to an aftermarket rearend to run them without significant pad knockback. The issue with any fixed piston caliper is that the rear axles can move in and out a bit with the c-clips. With a sliding caliper, it doesn't matter if there's a little play in the axle. But with a fixed caliper, you'd feel that as the brake pedal going to the floor and a momentary oh **** nothing is happening reaction.
But if you did convert to a bolt-in axle and ran a Wilwood Proportioning valve you could do the Wilwood 4-wheel kit with either 14 or 13" front rotors and 6-piston calipers and 12.8" rear rotors and 4-piston calipers...
