The Action Clutch Ironman Sprung clutch kit for the 2001 BMW 525i (2.5L RWD) is a race-focused single-disc assembly that includes a lightened flywheel. Built with American sintered iron friction and a dual clamp-load heavy-duty pressure plate, it delivers aggressive on/off engagement with enclosed spring retainers. Intended for track use, it increases holding capacity substantially and may produce light engagement noise or gear rattle.
