I have the ACT 2100 with their ACT sprung 6 puck ceramic disc on an ACT flywheel, if you want a review on that.

We really like the rigid hub (unsprung) 4 and 6-puck disks here. You will NOT feel a difference between the 4 or 6. We have played with them enough to find that the rumors of the 4-puck feeling worse than the 6 are untrue.

The 4-puck unit is very light, so will allow the synchros to work a little better at high RPM shifts.

The heavier the pressure plate, the bigger your clutch 'friction zone' will be with those. I would not recommend the 4 or 6-puck units on anything that is 2100lbs or lighter. 2600-2900 PPs work very well with them.

With the rigid hub though, you will get more engine harmonics and trans gear noise through your drivetrain. They can also chtter a bit when the car is idling.

One last thing- one of the main killers of a sprung disk are the springs. The rivots and springs seem to have a high failure rate. With an unsprung unit, you don't have all of those extra pieces that can break...

edit, oops, didn't realize you were looking at the units with the kevlar lining.
