AP Racing Radi-CAL Competition Front Kit 372mm - Tesla Model 3

The AP Racing by Essex Radi-CAL Competition Brake Kit is a front brake upgrade for the 2017-2023 Tesla Model 3. 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

Weighs roughly the same as OEM brakes, despite being considerably larger. 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 Tesla Model 3, the CP9660 caliper mounts radially on a dedicated bracket. 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. The caliper uses a commonly available 18mm thick pad shape. Ventilated, domed-back 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.
