What is the main difference between this rigid disc and a sprung clutch disc?

A rigid disc, like the one in this kit, has a solid hub with no springs. This allows for quicker shifts but results in harsher engagement compared to a sprung disc, which has springs to absorb some of the shock.

Is this clutch kit suitable for daily driving?

This kit features a rigid 6-pad ceramic race disc designed for demanding use and faster shifts. Engagement is harsher, making it less ideal for smooth, comfortable daily driving compared to a stock or milder aftermarket clutch.

Does this clutch kit come with a new pilot bearing and alignment tool?

This kit includes the ACT Heavy Duty Pressure Plate and the ACT Rigid 6-Pad Race Disc. It is recommended to check the manufacturer's installation guide or contact ACT directly to confirm if a pilot bearing and alignment tool are included or separately required.

Product Details

BM12-HDR6 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 6-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 6-pad rigid race disc, engagement is harsher, but shifting is faster. The 6-pad rigid race disc is recommended for larger clutch sizes to absorb more heat.
