    Agreed, they do feel different. I had an older ST and never had the TSB done for the soft motor mounts. Later STs and STs with the TSB performed had a restrictor added to the clutch line to help lessen shock to the driveline if you dump the clutch. If you released the pedal fast enough, it would "slap" the bottom of your foot since the pedal moved slower. This isn't the case on the RS, likely due to launch control.

    FWIW, Tasca shows the RS clutch as G1FZ-7B546-C and only spec'd for the RS. The ST shows as DV6Z-7B546-A.

    From my knowledge, the rs has a harder clamping force, and uses the same material for the clutch as the gt350. The rs clamping force is about 1.5x the force of the st from what I could find.
