The Super Street Pro is ideal for both the street and the track. We recommend it for cars up to 550 HP (depending on part number) with moderate engine mods and street tires. The kit is SFI-approved. Included is a high clamp load pressure plate, a dual-performance organic and ceramic disc for smooth engagement, and awesome holding power. Our kits are complete with a pressure plate, a dual-performance organic/ceramic disc, throw-out bearing (where applicable) pilot bushing (where applicable), and an alignment tool. If you are looking for a street-friendly yet track-proven clutch, the Silver Sport Transmissions by McLeod Super Street Pro is your best choice.
