ACT's Street discs are the most popular disc purchased. They feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs feature a reduced marcel for faster shift action to complement ACT pressure plates. Quiet operation with increased strength and reliability.

ACT Street disc Key Features- ACT carefully selects the right amount of cushioning between the linings to allow for good engagement characteristics without sacrificing performance.
- ACT Street discs feature premium friction material. With this material, the disc achieves better heat tolerance and faster recovery from overheating.
- Carefully broached splines to ensure exact fir onto the transmission input shaft for long spline life and better clutch release.
- Precision stampings for disc components are manufacturer using dedicated tooling. This allows ACT to offer the highest in quality and consistency.
- Top grade rivets are used to securely fasten the part together. Rivet design and materials are carefully selected for maximum strength.
- ACT spring retainers feature wraparound spring windows that provide support and reduce stress concentrations, which are common causes for failure. These spring retainers are offered on most ACT Street discs.
- Heavy duty torsional dampening springs are stronger in most cases than standard springs and are provided in the best sizes and spring rates to suit the application. Quiet operation is ensured from original equipment (OE) quality torsional dampeners.
- Spring windows on most ACT Street discs are heat-treated to resist wear, increase strength and reduce the chance of springs "popping" out.
- Most ACT spring-centered assemblies use bushings and cone springs, similar to factory clutch discs. This creates frictional dampening that improves clutch life and reduces noise.
This is a 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.
Recommendation:Recommended for street and race use.
Difference:Steel-backed linings for higher burst strength, reduced marcel for quicker shifts.
