Project C7 Corvette Stingray Z51: Improving Stopping With a Chevy Performance Big Brake Upgrade Kit

,

This is what the parking brake looks like- a miniature drum brake inside the rear brake rotor.

The Chevy Performance rear caliper is basically identical, except the mounting ears are longer to accommodate the bigger rotor.

The stock and Chevy Performance calipers are 4-piston Brembo units.

The C7 Corvette rear brakes are pretty large for a front engine rear drive car because of the C7’s 50/50 weight distribution. More weight in the back causes the rear brakes to share a larger percentage of the braking tasks; this is a good thing.

 

The Chevy Performance rear rotor on the left is significantly larger than the stock Z51 rotor on the right.

The Chevy Performance rotor is also a fully-floated two-piece rotor to avoid problems with thermal distortion and warping that the stock rotor might suffer from in extremely hard use.

  1. Thank you for the video and article regarding the Stingray upgrades. I have been looking at the Chevy brake upgrade but was hesitant due to Chevy performance article stating that the brake upgrade was not compatible with the z51 stock wheels for clearance. I saw your car in the video and read the article that you used the stock wheels. Therefore I wanted to ask if you had any trouble with the stock z51 wheels fitting the upgrade? Was a spacer needed? Thank you for any help or detailed pictures regarding brake clearance with stock z51 wheels.

  2. Which are you referring to as being heavier, the OEM units or the upgraded units? Do you know the actual weight of the upgraded calipers and rotors?

  3. What is the GM part number for this kit? My local GM Performance dealer was quite confused! The entire C7 project series was amazing and gave me inspiration to upgrade my 2019 Z51.

  4. So you did the video showing the b4 the Z51 brake upgrade. What about the after video (I can’t seem to find it). Also it appears that there are disclaimers for using this upgrade kit and it appears the spacer is not available.

    Please advise.

    Thanks in advance..
