ACT XT Performance street rigid clutch kit for 2007-2009 BMW 135, 335, 535, 435 and Z4 N54 models. It features ACT's Xtreme pressure plate - a heat-treated diaphragm design that raises clamp load and reduces deflection - paired with a lightweight rigid-hub street disc made from high-copper organic friction material and a heat-treated chrome-moly hub. The combination yields faster shifts with street-friendly manners. One-year warranty.
