I'm using a street performance clutch set from Zoom. It works just fine and stands up to the abuse a ~370 HP 360 can dish out. The only issue I have with it is that if I adjust the slop out of the pedal to less than 2" then with the pedal on the floor the fingers of the pp will contact the hub of the disk, it will wake you up in a hurry. ;)
I talked to Brewers about that and they have heard of this issue with a number of the three finger pp's out there. I had called them to see if I had the wrong z-bar or clutch fork, I didn't.
To ensure that the pedal will come all the way up when I take my foot off the pedal I put a piece of 2x4 under the carpet so it acts as a stop and that way i can adjust more of the slop out at the top. Not elegant but works fine and no one is to the wiser.
