The Pro+ system features a robust 2-piece, 6-piston caliper, perfectly paired with a 13" two-piece slotted and drilled zinc-plated rotor. This 6P caliper is equipped with D.O.T compliant dust and weather seals, ensuring durability in various conditions, and it utilizes the widely popular D0731 pad type. Each rotor comes pre-assembled with high-grade NAS stainless hardware, and we’ve included all the necessary mounting brackets, stainless braided hoses, and additional hardware for a smooth installation. The 13" Pro+ is designed to fit most wheels that are 17" or larger, making it a versatile choice for your ride. It's a great fit for the 1988-96 Chevy Corvette (C4).
