The ACT XACT Prolite flywheel for 1990–2005 Mazda Miata is a lightweight, low-inertia option tuned for faster throttle response and improved acceleration in road or rally use; note 1990–1993 cars require the 1.8L clutch. Materials are distributed for strength, heat tolerance and rigidity, and the unit is serviceable and resurfacing-friendly. Prolite tradeoffs include reduced low-speed drivability and a one-year warranty.
