High-performance compound brake discs on the BMW M3 Sedan.
Developed and tested on the Nürburgring's Nordschleife: the high-performance compound brake discs fulfil the toughest of requirements on braking deceleration, durability, wet-weather performance and heat response - requirements usually only met by a sports car. These fully floating and perforated brakes react quickly and precisely, and thanks to the cross-drilled brake disc and partial use of aluminium, the system is incredibly lightweight. The result? A high-performance braking system for better everyday suitability.
