AP Racing Competition Rear Kit 325mm - C5 Corvette

The AP Racing by Essex Competition Brake Kit is a rear brake upgrade for every 1997-2004 C5 Corvette, including Z06. It pairs AP Racing CP8350 racing calipers with 325 x 32mm, 70-vane AP Racing J Hook discs on fully floating aluminum hats, built for track days and competition driving. Clears OEM C5 Z06 rear 18 inch wheels.

Why upgrade

Each caliper weighs 4.8 lb without pads, against 6.2 lb for the factory caliper. The 20mm pad is thicker than the 16.7mm factory pad, so it lasts longer and absorbs more heat between changes. Every component is designed to resist the heat of extended track sessions. Pistons are sized to work seamlessly with the OEM master cylinder and ABS.

Caliper and disc construction

On the C5 Corvette, the CP8350 caliper mounts radially on a dedicated bracket at 152mm centers with a 44mm offset, with an M10x1.0 inlet thread. There are no dust boots to burn up at track temperatures. Pads change with one bolt, with no caliper removal. The championship-winning 70-vane AP Racing J Hook discs are fully floating. The discs use anti-knockback, anti-rattle attachment hardware. The disc metallurgy is designed for the temperatures seen on track, for a long service life. Spiegler stainless steel brake lines with a clear sheath reduce compliance compared with the OEM rubber lines. The caliper uses a commonly available 20mm thick pad shape.
