The Stage 3.5 System uses the Power Plus I Pressure Plate with Clutch Masters New Formula Button disc. This clutch is designed for the street enthusiast or weekend racer who plans to abuse their vehicle on an occasional basis and have a spirited driving style. The FX350 clutch system has a higher holding capacity than a segmented Kevlar lining without compromising the street friendly characteristic Clutch Masters is known for. For year s enthusiast have had to compromise durability for drivability and vise versa, however with Clutch Masters New Formula button we have closed the gap between these two tradeoffs.

All of the Stage upgrades by Clutchmasters can be ordered with a dampened or Rigid disc. Most of the time for street applications we are going to recommend the dampened or sprung center hub. With the dampened hub, there are small springs that buffer the engagement of the clutch, which produces a smoother engagement. The rigid disc can take more abuse but is a little bit rougher on engagement and is only recommended for track use or a car used for a lot of drag racing.
