EBC Brakes™ has engineered its own range of increased pressure heavy-duty diaphragm clutch springs to replace tired or worn original units and these are included free of charge in the SRK series kit. New SRK complete kits include aramid fiber-lined friction plates, steel separator plates, and springs to provide a street-going kit for high-performance street and road race use much similar to the DRC program for off-road. Some of the kits will now feature new diaphragm springs as used in many larger new bikes to provide a complete clutch rebuild kit for every sportbike possible.
