The ACT Prolite Flywheel is a high-performance upgrade engineered to maximize engine responsiveness and acceleration in the BMW M3 E46. Designed with motorsport precision, this lightweight component reduces rotational mass and inertia, resulting in faster throttle response and sharper gear engagement. Constructed from heat-treated forged material, the Prolite Flywheel delivers exceptional strength and reliability under high-stress conditions, making it ideal for both road racing and high-performance street driving.
Its one-piece CNC-machined structure ensures uniform heat transfer from the clutch disc and minimizes failure points, reducing the risk of warping or ring gear issues. The induction-hardened ring gear further enhances durability, while dynamic balancing guarantees smooth and consistent high-RPM performance. This flywheel is also fully serviceable and can be resurfaced, extending its usable life without the need for replacement parts.
Engineered for 2001–2006 BMW M3 models, the ACT Prolite Flywheel provides a significant improvement in drivability and performance compared to stock flywheels, offering enthusiasts a responsive, durable, and track-proven solution for their performance builds.
