I originally had the Centerforce Dual Frictions clutch. It worked fine when it worked, although on really hard shifts it did not hold the power nearly as well as the RPS. The Centerforce started slipping really bad so I took the trans off and found out what the problem was. Bad design, the wieghts that are on the forks (which is their unique design) was the problem. The wire that ties these wieghts together does not join at the end and as a result the half of the wieghts had gotten jamed between the pressure plate housing and the forks. The result was like half of the clutch was not engaged. I spoke with several people including Greg Dupree and it sounds like this is pretty common. I would stay away from the Centerforce. If you have a TT you have a booster on the clutch and with the RPS it is easy to press the pedal and it holds the power.
