Advanced Clutch Technology (ACT) has released performance clutch kits for the 2002-2004 Porsche 911 Carrera and Carrera 4, 2002-2004 Porsche 911 Targa and the 2000-2002 Porsche Boxster S.
ACT’s new clutch kits for the Porsche applications listed above include a Heavy Duty pressure plate, a choice of disc, release bearing, pilot bearing and alignment tool. The Heavy Duty pressure plate features a precision stamped cover for maximum consistency and rigidity, and a thicker casting with a wider friction surface area that allows for higher heat capacity and longer clutch life. The pressure plate also incorporates hardened diaphragm fingers for decreased bearing surface wear and is designed within the optimum working range to maximize clutch life, clamp load and release travel.
The ACT Street clutch kits combine the Heavy Duty pressure plate with a rigid-hub street disc. The disc features special performance organic friction materials able to withstand increased heat and abuse, steel-backed linings for high-burst strength and modifications engineered for quicker shifting. The ACT Street clutch kits provide a moderate and consistent pedal feel, smooth engagement and significantly improved durability. These kits meet SFI Spec 1.1 and have increased torque capacity up to 560 lbs./ft.
The ACT Race clutch kits combine the Heavy Duty pressure plate with a cerametallic Xtreme Race disc, which is available in 6-pad and 4-pad rigid-hub designs. These discs are very durable while allowing for quick shifting. The Xtreme Race discs are for high-powered engines and recommended for track use only. The ACT Race clutch kits meet SFI Spec 1.1 and will hold 714 lbs./ft. of torque.
