South Side Performance is offering yet another first for the EVO SST, our SSP Pro Series Clutch Packs for the TC-SST Dual Clutch Transmission. This component is another in a line of SSP products that strengthens and supports high horsepower EVO X SST’s.

In months of testing SST’s running very aggressive power combinations, SSP has tirelessly worked to create a wide array of components for the TC-SST transmission in order to increase its ability to support high horsepower applications. SSP has experience with high horsepower AWD cars and knows that clutch packs are going to be a point of weakness once certain power levels are exceeded. So, instead of responding to failures after they happen, SSP has designed a solution to prevent clutch failures from happening in the first place.

The Pro Series Clutch Disc has 30-40% more gripping force over the stock clutch discs, due to an increased surface area. The disc itself is a complex compound of cotton, carbon fiber, synthetic organic fibers, and other materials. In fact, these new clutch discs are made out of the same material we use in our GTR 700whp clutch discs. These new materials add to the strength of the discs while still retaining the properties that allow it to hold up in the submerged oil environment of the TC-SST’s valve body. This particular compound has been tested to hold 420-475 crank horse power and 410 foot pounds of torque at 200°F. At these power levels the transmission’s fluid temperature will determine the amount of clamping force the clutch discs are able to exert. To obtain and maintain this power level other considerations, such as the SSP oil cooler kit, should be entertained as well.

*****Important: Installation of these clutches will require internal transmission work, professional installation is advised.*****
