The standard high-performance braking system of the new BMW M6 Gran Coupe guarantees outstanding stopping power matching the overall performance of the car. The well-known BMW M compound rotors have been further improved for the new M5 and M6 family. These rotors thermally separate the central hub (constructed of aluminum) and the vented / cross drilled cast iron rotor discs. As a result, the rotors are free to expand and contract without warping. The diameter of the brake rotors is 15.7 inches (400 mm) at the front and 15.6 inches (396 mm) at the rear. The six-piston fixed calipers are radially bolted to the pivot bearing and are painted blue metallic complete with the M logo. Together, the M brake system has been tested to provide exceptional performance and modulation, fade resistance, and pedal feel.
The new BMW M5 and M6 family will be the first cars in the history of BMW M to be offered with optional M Carbon-Ceramic brakes, which become available with Spring 2013 production. These new brakes are without parallel and take the carsΆ stopping power to a new level – especially on the race track. The brake rotors measure 16.1 inches (410 mm) in diameter at the front and 15.6 inches (396 mm) at the rear. Made from a carbon-fiber ceramic composite, the rotors boast even greater resistance to heat combined with significantly reduced rotating masses. The M Carbon-Ceramic brakes are 42.8 lb (19.4 kg)
lighter than the standard brakes, yet the innovative material also displays exceptional resistance to wear, and the operating life of the rotors is several times that of conventional equivalents. The optional M Carbon-Ceramic system also sees six-piston fixed radial calipers at the front teamed with single-piston floating calipers at the rear. The M Carbon-Ceramic system can be easily identified through the wheels by the special gold-colored calipers.
The M6 Gran Coupe features a unique wheel and tire combination with 20-inch M6 Gran Coupe-specific double-spoke forged light alloy wheels fitted with giant ultra-high performance summer tires, front and rear.
