The ACT XACT Prolite flywheel for 2007 Ford Mustang is a lightweight, low-inertia option tuned for quicker throttle response and improved acceleration. Prolite models suit road or rally use where faster engine response is desired, with some trade-off in everyday drivability. Materials are distributed for strength, heat tolerance and rigidity, and ACT's serviceable design allows resurfacing instead of replacement.
