The ACT XACT Streetlite Flywheel is a precision-engineered upgrade for BMW 135i and 335i models from 2009–2013, delivering sharper throttle response and enhanced driveline performance. Constructed from heat-treated forged steel, this flywheel combines exceptional strength and rigidity with reduced weight, providing quicker acceleration and smoother clutch engagement under demanding conditions.
Its one-piece design minimizes failure points and promotes uniform heat transfer across the clutch surface, improving long-term reliability and reducing wear. The induction-hardened ring gear extends service life, while CNC machining and dynamic balancing ensure stable, vibration-free operation at high RPMs. With its optimized material distribution, the Streetlite Flywheel maintains excellent heat tolerance and structural integrity, making it ideal for both spirited street driving and competitive racing.
This flywheel is fully serviceable and can be resurfaced without additional components, offering a cost-effective maintenance solution. Engineered to outperform stock components, the ACT XACT Streetlite Flywheel provides a superior combination of strength, responsiveness, and longevity — a trusted upgrade for performance-focused BMW enthusiasts.
