Unfortunately, I had bad high RPM lock out with the Centerforce Dual Friction. Replaced it with another manufacturers clutch and I have no more high RPM shifting issues. The Centerforce worked great on my Talon TSI AWD, but not on my Evo. My vote goes for other.

When you say "Lock out" what do you mean exactly? Will it not go into 4-5-6 when at high rpm? I beleive i have heard of this before, and it was something to do with the weight's on the PP.

It simply would not go into gear or I would have to muscle the shifter to get it into gear at my 7,500 RPM shift point. The clutch would just not disengage at high RPM. At lower RPM's it would do fine.

My previous experience with Centerforce has been great.. Not too sure that the Evo clutch has proven itself yet..

HOWEVER, with the centerforce clutch, it uses flyweights to assist the diaphragm spring pressure, so at high RPM, you could get lockout if you don't remove the restrictor as it screws with your (Brain-lag human shift) timing and ability to adequately engage and disengage the clutch. I did see this on another car that had a hydraulic clutch setup with a restrictor in it.

Thanks for the info. When you speak of this Restrictor, are you talking about the one that is in the clutch line? If so, this has been removed, and a stainless line is in place.. I will speak to Centerforce about this problem. Thanks

Yep thats the restrictor I'm talking about. Just verify anything you want to do with the manufacturer.
