J56 brakes on C7 Grand Sport
Hello, my 2019 C7 Grand Sport came with J56 brakes based on the car's VIN. Also, I don't think I have the Z51 package. Can I install J55 brakes on my car? I believe J56 are the larger, heavy duty rotors compared to the J55 but looking to replace all pads and rotors (front and rear). Any advice or additional thoughts on this would be appreciated. As of now, I am leaning toward powerstop brakes as long as I can confirm they are a good fit for my car. I am looking on rockauto and summit racing for these parts and can't figure out if they would be compatible with J56.

J55 is a downgrade plus you'd have to replace the calipers. Stick with J56.
