ACT 07-09 BMW 135/335/535/435/Z4 N54 XT/Race Sprung 6 Pad Clutch Kit

Item SKU: BM14-XTG6

ACT BM14-XTG6 Transmission Clutch Kit for 2007-2009 BMW 135i, 335i, 535i, 435i, and Z4 models with the N54. This is ACT's Xtreme pressure plate paired with a sprung 6-pad ceramic race disc for high-horsepower street or race use.

• Kit type: Newly manufactured single-disc clutch kit with an ACT Xtreme pressure plate and spring-centered 6-pad race disc.
• Disc: Select ceramic friction material handles heat, while the sprung hub helps damp torsional vibration. The disc's wraparound spring windows and thicker retainer stampings support the damper springs under harsh use.
• Engagement: Expect aggressive engagement, moderate-to-heavy pedal effort, and OE to mild gear rattle. This stuff is built around faster shifts, not stock-like takeoff feel.
• Pressure plate: ACT's exclusive diaphragm design increases clamp load while reducing deflection. The diaphragm receives a four-stage heat treatment, and the precision-stamped cover adds rigidity and consistency.
• Use: Recommended for high-horsepower street or race cars. Friction life is moderate, with clutch life supported by the diaphragm design.
• Balance: Each kit is 100% clamp-load tested and dynamically computer balanced for smooth operation at high RPM.

If your N54 BMW has moved beyond a street-oriented organic disc, the BM14-XTG6 trades some civility for heat tolerance and quicker engagement. No more expecting a 6-pad ceramic setup to behave like the factory clutch. It is a sprung race disc, so there is still torsional damping in the driveline, but the engagement character is direct and the pedal is noticeably heavier.
