Competition Clutch's Stage 1.5 Clutch Kits are an affordable option for slightly modified vehicles or enthusiastic drivers with stock power. They provide up to a 30-40% boost in torque capacity while retaining the feel of a stock clutch pedal. Avoid using with additional forced induction like turbos, superchargers, or NOS systems. The 1500 Series kits come with a Competition Clutch pressure plate, full face organic performance disc assembly, throw out bearing (where applicable), pilot bearing/bushing (where applicable), and an alignment tool.
