No experience yet - Pro Jackstand class - but I am planning to run one. FWIW, I'm told it's a potential problem w big HP/Cam and an aluminum flywheel...
Now that I think about it, I had a conversation with McLeod and the reccomended the RXT. I've only got 666hp and the RST will certainly hold that power. The problem is the road racing. From my understanding, the RST is more of a street/strip clutch. The clutch is made of a more organic disc and will fade with repeated abuse. The RXT is a more agressive ceramic type design made for more torture. The 1000hp rating should hold up to about anything around here. The pedal effort isn't any worse than my Centerfoce dual friction.
That's a myth. I've got a couple thousand miles on mine. I noticed a shudder at first but I was getting used to the clutch. I haven't heard any chatter. I'm happy with mine. Good drivability and made to put up to the torture I insist on.
