The ACT Streetlite Flywheel is a lightweight, precision-engineered upgrade that delivers improved throttle response and acceleration for BMW 128i and 325i models from 2006–2013. Crafted from heat-treated forged steel, this flywheel combines strength, heat tolerance, and rigidity, making it a dependable choice for both spirited street driving and drag racing environments. Its properly distributed mass reduces rotational inertia while maintaining structural integrity, helping drivers achieve quicker revs and more controlled power delivery.
With a one-piece CNC-machined construction, the Streetlite Flywheel minimizes failure points and ensures uniform heat transfer for consistent clutch engagement. The induction-hardened ring gears provide exceptional wear resistance and extended lifespan, even under demanding conditions. Dynamically balanced for smooth operation at high RPMs, it enhances drivability and reduces vibration or gear rattle commonly found in OEM components. Serviceability is straightforward—the flywheel can be resurfaced without replacement parts, offering long-term reliability and value.
Engineered to meet ACT’s exacting standards, this flywheel provides the ideal balance of performance, durability, and refinement. Whether for everyday performance driving or competitive use, the ACT Streetlite Flywheel delivers consistent results with lasting reliability.
