What difference in performance is there between sport discs and the full race kit?
The PFM Brake Systems Sport discs are a direct replacement disc and are designed to work with standard calipers. They will improve the brake performance because of the higher coefficient of friction and heat transfer properties over stainless steel discs, which is sufficient for motorcycles fitted with a good quality well maintained OE calipers. The race kit replaces the standard disc with a 320mm diameter narrow pad track disc that gives the same effective operating radius as a conventional depth 330mm diameter disc (without the increase in gyroscopic force that a 330mm disc would produce). A 6 piston ‘machined from solid’ caliper with a narrow pad depth developed for the narrow pad track disc provides the minimum deflection within the envelope available, along with the lowest residual drag possible. This provides the highest level of performance available from a ferrous (non carbon) brake system. Wave Discs? In the main we have not made a ‘wave’ disc because of the high pad wear rate
