ACT’s new clutch kits for the B5 S4 and C5 A6 include a Heavy Duty or Xtreme pressure plate, a choice of disc, Streetlite flywheel, release bearing, pilot bearing and alignment tool. The Heavy Duty and Xtreme pressure plates incorporate hardened diaphragm fingers for decreased wear and provides a 26% (HD) or 41% (XT) increase in clamp force over the stock unit.
The ACT Street clutch kits combine either a Heavy Duty or Xtreme pressure plate with a performance organic street disc. The disc features premium 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 kit provides 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 515 ft.-lbs with the Xtreme pressure plate.
The ACT Race clutch kits combine the either a Heavy Duty or Xtreme pressure plate with a cerametallic Xtreme Race disc, which is available in a 6-pad spring-centered design. This disc is highly 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 are rated to hold up to 660 ft.-lbs. of torque at the crank with the Xtreme pressure plate.
The Streetlite is a lightweight, single-mass upgrade to the dual-mass OE flywheel for these applications. It is designed for performance and affordability, without compromising a smooth idle. The one-piece, forged Chrome-moly steel flywheel is CNC-machined and features induction-hardened, integral ring gear for increased durability. ACT flywheels are engineered for strength and allow cost-effective resurfacing.
Driver and spectator safety are a top priority at ACT. Each ACT flywheel is certified to meet SFI Specification 1.1 standards, making them legal for competition where SFI 1.1 certification is required or recommended. XACT flywheels come complete with an official SFI sticker and serial number, as required for certification.
The 600950 XACT Streetlite flywheel weighs 15.3 pounds, which is 42% lighter than the stock flywheel. It provides quicker engine response and acceleration, while being significantly lighter than stock.
