Description

This clutch kit is required if you are running the K to BMW ZF Flywheel.

Sprung organic disc setup is for 6 speed transmissions only.

- We recommend the sprung organic disc with the HD pressure plate up to 400whp.  If you are planning to track the car, we recommend going with a ceramic disc option.

 

 Description

Performance street disc and the most popular disc purchased. It features premium organic materials with high copper content for better heat transfer. Performance street discs allow for quicker shifting and smooth engagement. These discs feature a reduced marcel for faster shift action to complement ACT pressure plates. ACT spring-centered assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening, which improves clutch life and reduces noise. Quiet operation with increased strength and reliability.

Feel: Smooth engagement, quicker shifts, OE to mild gear rattle;

Life: Premium organic composite friction blended for high heat tolerance, increased burst strength, faster recovery from overheating and less wear of mating surfaces;

Quality: Spring retainers feature heat-treated wraparound spring windows that provide support and reduce stress concentrations that are common causes for failure;

Recommended Use: Recommended for street and race use;

ACT Difference: Steel-backed linings for higher burst strength, reduced marcel for quicker shifts;
