The ACT XACT Streetlite flywheel for 2008–2013 BMW 128i (E82/E88) 3.0L inline-six is a lighter, high-strength replacement that reduces rotational inertia for crisper throttle response. Materials are distributed for maximum rigidity, lower inertia and improved heat tolerance, making it suitable for spirited street driving or drag use. Streetlite flywheels are serviceable and can be resurfaced rather than replaced.
