The Clutch Masters FX400 6-puck clutch kit for 1997–2003 BMW 540 (E39) 4.4L is a conversion-style upgrade built to work with a Clutch Masters-specific flywheel (267mm). With roughly a 170% increase in holding capacity, the sprung ceramic design aims for long life and strong heat dissipation while retaining some daily drivability. This kit requires the dedicated Clutch Masters flywheel conversion for proper fitment.
