You can choose the size of disc that you require below.
Alcon brake discs are available in a wide range of sizes to suit all categories of Motorsport from clubman single seaters through to NASCAR, Touring cars and WRC. To give optimized cooling the vanes in the disc are curved and the addition of grooves to the friction face helps to remove dust and gasses which can reduce braking efficiency.
Constructed from a cast iron alloy which is unique to Alcon and has been developed to increase friction, reduce wear and offer resistance to thermal shock. The high quality brake rotors from Alcon are designed to be bolted to a mounting bell (top hat) to form a 2 piece brake disc set up.
