TAROX Rear Bespoke Brake Discs - M3 F80 / M4 F82 F83

Rear performance rotors for BMW M3 F80 and BMW M4 F82 F83

Upgrade your rear stopping power with Italian-made two-piece vented rotors designed for fast road and track-day use. Precision engineered from solid billet steel then heat treated and hand finished, these rear discs deliver consistent braking, superb thermal stability and long-term durability while retaining factory fitment.

Each rotor is built to order and supplied as a handed left and right pair with side-specific cooling features. The surface is ground to an ultra-tight tolerance of approximately 0.015 mm so the discs run true under heavy load. Ultimate tensile strength is rated at 57 kg per square mm, far exceeding typical OE standards.
