New Products: 390mm and 378mm Radi-CAL Competition Brake Kits for C8 Corvette Z06

When it initially broke the long standing Corvette mold in 2020, the mid-engined C8 Stingray was already a rolling inflection point for the brand. However, with a even wilder exotic-inspired flat-plane crank V8, Chevy's latest Z06 throws yet another chapter of the old Vette rulebook right out the window. To help reign in all 670 horsepower from the 5.5L high-winding powerplant, we are thrilled to release our larger 390mm and 378mm Competition Brake Kit options!

Enjoy some installed images of the largest available CP9668 front / CP9669 rear kits, along with full details outlined below.
