ACT Advanced Clutch XT/Perf Street Sprung Kit - BM13-XTSS

If you're looking to upgrade your BMW's clutch system for both street and race applications, the ACT Advanced Clutch XT/Perf Street Sprung Kit (BM13-XTSS) is engineered for enthusiasts who demand performance without compromise. This kit features an Xtreme pressure plate that’s perfect for spirited driving, ensuring your clutch can handle the most demanding situations.

Why Choose the BM13-XTSS?

The Xtreme pressure plate utilizes a unique diaphragm design that boosts clamp load while minimizing deflection, significantly enhancing clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring durability and performance that you can rely on. Precision cover stampings provide the rigidity necessary for consistent performance during high RPMs.

The Performance street discs included in this kit are among the most sought-after options available. Constructed from premium organic materials with high copper content, they excel in heat transfer and durability. The steel-backed lining enhances burst strength, while the reduced marcel ensures quicker shifts, giving you that extra edge on the road or track.
