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 pressure plate, a dual performance organic/ceramic disc, throw out bearing (where applicable) pilot bushing (where applicable) and 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.
