I really liked my exedy mach 500. It is a bit heavier than stock but not that big of a deal. I now have a McLeod RST and I'll be pulling it out and having it rebuilt as an RXT. If you think you may try drag racing, don't get the RST. My car is good for one pass, then it gets too hot and it gets impossible to shift. The floater plate rattle drives me nuts as well so unless you are going to make the power to require a twin disc, it isn't worth the noise.
