MW carbon/carbon brakes offer the advantage of an extremely light-weight rotor with superior stopping power ability. When compared to a standard kit with drilled steel rotors, a Carbon/Carbon brake kit can save you as much as 10 lbs of rotating weight. Carbon/Carbon brakes are unique because both the disc and lining are made of the same material and do not suffer brake fade at elevated operating temperatures as with normal rotors and friction materials. The square drive lug system allows for the expansion of the aluminum mounting hat without applying pressure to the rotor. MW brakes are produced from BFG 2D PAN knit Carbon/Carbon that is superior to the random chopped fiber used by others. MW Carbon/Carbon kits include MW race proven 4 piston calipers with hard anodized pistons, carbon brake linings w/ stainless heat shields, billet aluminum mounting brackets, and all the required fasteners. Extensive race testing has proven the outstanding wear characteristics of the BFG Carbon/Carbon material. Brake Technology has changed dramatically over the past few years and Mark Williams Enterprises is in the forefront.
