Big rear brake suggestions

Hey y'all, I'm about to get my big brake upgrade going once I buy some new wheels. I don't want to run 2 in spacers for my current wheels to fit. Anyway, Does anyone know of any rear brake upgrade that would involve maybe a four piston caliper or a two piston side by side caliper setup?

FYI, Everything bolted on without any issues. I'm even able to use the stock bolts from the caliper bracket. The only problem I have is that my wheels won't clear the calipers and I want to get a new set so I don't have to run wheel spacers. The picture is just a mock-up. You can see the old rotor on the floor. Unfortunately, I couldn't finish the install because of the wheel fitment issues. I guess the only bright side, I'm going wheel shopping tomorrow LOL

CTS-V brakeswap.com has a kit for the front & rear of the 07-14 & 15-20 full size SUV & trucks using bolt on adapters.

Using the front calipers from Brembo’s carbon fiber C6 ZR1 6 pot Vette set up and retaining the standard Vette pads, CTS-V.com uses the same 16.25” rotors as GM’s bolt on Brembo kit for half the price. You’ll also get titanium pistons in ZR1 calipers.

The rears use Brembo C7 4pot Vette calipers with OEM discs, which is ok because they’re already bigger than the front OEM discs.

I’ve got the front set up but still haven’t installed them. They need .5” spacers with OEM rims.


Brembo make a 4 pot kit for the rear that’s $5k as well as Willwood which is said to require frequent rebuilding that no one does unless they’re being track’d.

You can get the 2018 camaro ss rear calipers they are cheaper then the corvette calipers even though they're the same. Here's a pic of the ones I'm putting on my sierra.

any changes to the brake line needed? dont see it mentioned
i went ahead and ordered the brackets, calipers, pad/hardware kit
hoping the fixed caliper will last longer as opposed to the floating

will likely stick with the 2021+ ppv front set up

Not sure on your application but on the k2xx the brake lines stay the same
