The Pro+ system features a robust 2-piece, 6-piston caliper, expertly mounted to a 13" 2-piece rotor that's both slotted and drilled, all finished with a zinc plating for added durability. This 6P caliper is equipped with D.O.T compliant dust and weather seals, and it utilizes the widely appreciated D0731 pad type. You'll find that the rotors come pre-assembled with high-grade NAS stainless hardware, and all the necessary mounting brackets, along with stainless braided hoses and additional hardware, are included for your convenience. Designed to fit most 17" or larger wheels, the 13" Pro+ is a perfect match for the 1988-96 Chevy Corvette (C4).
