Advanced Clutch Technology (ACT) is pleased to announce our new Streetlite and Prolite flywheels, for the 2001-2006 BMW M3 (E46).
These flywheels are lightweight, single-mass upgrade to the OE dual-mass flywheel for these applications. They are designed for performance and affordability, without compromising a smooth idle. These one-piece, forged Chrome-moly steel flywheel are CNC-machined and feature 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 601010 XACT Streetlite flywheel weighs 15.1 pounds, which is 40% lighter than the stock flywheel. The 601015 XACT Prolite flywheel weighs 9.9 pounds, which is 60% lighter than the stock flywheel. These flywheels provide quicker engine response and acceleration, while being significantly lighter than stock.
