AP Racing Radi-CAL ENP Competition Front Kit 372mm - Gen 5 Camaro

The AP Racing by Essex Radi-CAL Competition Brake Kit with ENP (electroless nickel plated) calipers is a front brake upgrade for the 2010-2015 fifth generation Camaro. It pairs AP Racing CP9660 Radi-CAL Pro5000R six-piston calipers with 372 x 34mm, 72-vane AP Racing J Hook discs on fully floating aluminum hats, built for track days and competition driving.

Why upgrade

The kit removes about 9-12 lb of unsprung weight from the front of the car compared with the OEM (depends on which the OEM caliper is being run). Each caliper weighs 6.2 lb without pads, against 9 lb for the factory six-piston ZL1/CTS-V caliper. Each two-piece disc weighs 19.1 lb, compared with 25 lb for the original 370mm disc. The 18mm pad is thicker than the 15.8mm factory pad, so it lasts longer and absorbs more heat between changes. The ENP (electroless nickel plated) finish is very durable and easy to clean. 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 Gen 5 Camaro, the CP9660 caliper mounts radially on a dedicated bracket at 180mm centers with a 42mm offset, with an M10x1.0 inlet thread. 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. Pads change with two bolts or a quick-change spring clip, with no caliper removal. The championship-winning 72-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.
