Clutch Disc of your choice

Performance Street Disc
ACT's Performance Street friction surface is SFI certified and is an excellent choice for modified, street driven cars and race cars. The SS disc provides quicker engagement than a stock surface and is quiet compared to other, more aggressive, friction surfaces. The sprung hub uses bushings and cone springs similar to OEM clutch discs; this creates frictional dampening that improves clutch life and reduces noise.
Holds up to 567 ft/lbs @ the crank

Solid Street Disc:
ACT's Solid Street Disc is SFI certified and is an great choice for modified, street driven cars and racecars. The Solid Disc features an organic full faced friction surface mounted on a solid hub. This disc will be louder then a sprung unit and will have harsher engagement with some chatter. The solid hub will put more shockload on the transmission then a sprung hub would. The Solid Street Disc is ideal for the driver looking for a a full face organic disc clutch with positive engagement.
Holds up to 567 ft/lbs @ the crank

6-Puck Sprung Race Disc:
The ACT 6-Puck Sprung Hub Race Disc is SFI certified, so it is legal for all forms of racing that require SFI compliance. An ACT G6 race disc has a very durable friction surface with good spline life. The G6 was designed for a highly modified car that is drive to, on and from the track, as long as harsher engagement is acceptable. The sprung hub helps to reduce driveline shock and be relatively quiet compared to an unsprung hub, though the G6 can still be noisier than a full face disc and will have some chatter.
Holds up to 726 ft/lbs @ the crank

4-Puck Sprung Race Disc:
An ACT 4-Puck Sprung Hub Race Disc has very harsh engagement and is designed for road race cars only. A G4 friction surface has good durability and spline life characteristics under normal use. The sprung hub helps to reduce driveline shock and be relatively quiet compared to an unsprung hub but will definitely have chatter. The ACT G4 is SFI certified, so it is legal for all forms of racing that require SFI compliance. Fred Beans Parts does not recommend the G4 for a street driven car.
Holds up to 726 ft/lbs @ the crank

6-Puck Solid Race Disc:
The reduced inertia of the ACT 6-Puck Solid hub allows for very fast shifts at the expense drivability. An ACT R6 race disc friction surface has very good durability but will have shortened spline life. ACT designed the R6 for a highly modified track cars where harsher engagement is expected and some clutch chatter is not a problem. The 6-puck layout of the R6 will absorb, and dissipate, more heat than a 4-puck unit. The ACT 6-Puck Solid Hub Race Disc is legal for all forms of racing that require SFI compliance. Fred Bean Parts does not recommend the R6 for any road going car.
Holds up to 726 ft/lbs @ the crank

4-Puck Solid Race Disc:
The ACT 4-Puck Solid Hub Race Disc is legal for all forms of racing that require SFI compliance. The biggest benefit of the ACT 4-Puck Solid Hub Race Disc is its extremely fast shifts thanks, in part, to its reduced inertia. An ACT R4 race disc friction surface has good durablity but will have shortened spline life. ACT designed the R4 for a heavily modified drag race or road race cars where extremely harsh engagement and clutch chatter is expected. Fred Beans Parts does not recommend the R4 for any road going car.
