Overview

The AP Racing by Essex Radi-CAL Competition Brake Kit is a front brake system for every C7 Corvette from 2014 to 2019: Stingray, Z51, Grand Sport, Z06 and ZR1. It fits AP Racing CP9668 Radi-CAL Pro5000R six-piston calipers and 372 x 34mm CP6084 discs with 84 directional vanes, giving the C7 a lighter, longer lasting front brake for track use.

Why upgrade

The C7 is fast enough to overwhelm its factory iron brakes in a long session, and the carbon ceramic option is costly to replace. This kit saves about 8 pounds of unsprung weight from the nose compared with the base and Z51 brakes and about 12 pounds compared with the standard Z06 iron brakes. Each caliper weighs 6.9 pounds against 9.8 to 10.4, and the floating disc weighs 19.1 pounds against up to 24.2. Compared with the Z07 carbon ceramics, it adds about 3 pounds per corner while bringing far cheaper consumables.

Caliper and disc construction

The CP9668 is a radial-mount Radi-CAL caliper with an asymmetric, computer-optimized body in hard anodized aluminum. Stainless pistons, anti-knockback springs and low-drag seals keep the pedal firm. The CP6084 discs ride on 6061 hard anodized aluminum hats with fully floating hardware. Pistons are sized for the OEM master cylinder and ABS.
