Lots of people are running cat secondary. With lots of success. Fett Brothers has the shaft for $135. Give 'em a call.

I think the recent snow tech had a piece on cat clutches on zx chasis sleds.Just glanced through the mag but i think it's in there.

I have a Cat sec in my 99 MX6.  I had it machined by Hitech (machined spline into clutch).  It is also equipped with the ER kit and a straight 47 helix.  Yoiu will have to move your engine over some.  I have a Sled Pro alignment tool and moved the engine over the equivalent of three thick and one thin AC clutch shims (sec spacers from AC dealer).  I am also running HC`s.  Seems to work well although I am still working on final calibration.  should have all ready this weekend.
