Advanced Clutch Technology (ACT) is pleased to announce our new Streetlite flywheel, the 600950, for the 2004-2009 Audi S4 (B6 and B7) 4.2L V8.
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.
