AP Racing Competition Front Kit 325mm - C6 Corvette

The AP Racing by Essex Competition Brake Kit is a front brake upgrade for every 2005-2013 C6 Corvette. 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 C6Z06 front 18 inch wheels without spacer.

Why upgrade

The kit removes about 20 lb of unsprung weight from the front of the car compared with the OEM brakes. Each caliper weighs 4.8 lb without pads, against 10.1 lb for the factory caliper. Each two-piece disc weighs 14.93 lb, compared with 21.8 lb for the original 325mm disc. The caliper takes a 20mm thick pad for long life and heat tolerance. 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. It works with the OEM rear brakes or a matching AP Racing rear kit.

Caliper and disc construction

On the C6 Corvette, the CP8350 caliper mounts radially on a dedicated bracket at 152mm centers with a 44mm offset, with an M10x1.0 inlet thread. 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. Stainless steel pistons keep heat out of the brake fluid for a very firm pedal. Anti-knockback springs behind the caliper pistons limit pad knockback. The anodized caliper finish resists wear and deterioration at high temperatures. Stainless steel caliper hardware gives a long service life even with frequent pad changes. There are no dust boots to burn up at track temperatures.
