Many people do the RST clutch and like them but I didn't like mine and replaced it within a 1000 miles.
Mine had vibration problems at low RPMs.
I also found that it did not grab immediately like my old Centerforce DYAD did and it felt like I was riding the clutch at times. The engagement felt vague.
I went back to the DYAD and what a difference.
Your mileage may vary and you may very well like the RST.
Not me though.
Thanks for the advice. I will definately check the centerforce out.
