ACT 01-06 BMW M3 E46 XACT Flywheel Streetlite

The ACT XACT Streetlite flywheel (MPN 601010) is a lightweight chromoly steel flywheel designed to reduce rotating weight, allowing the engine to respond faster, rev easier, and provide improved acceleration. It is the most durable flywheel offering from ACT and is preferred for street or drag racing due to its material distribution for maximum strength, lower inertia, good heat tolerance, and rigidity. ACT flywheels are serviceable and can be resurfaced. This Streetlite version prioritizes driveability compared to the Prolite version which is lighter but more race-focused. Gear rattle is expected with this single mass flywheel conversion.
