I may be incorrect or others may disagree, but I would venture to say that the ones who feel the stock setup is the best are either running the stock POS track w/ or w/o studs or are not adding studs altogether. I think if you addressed the traction issue on the RX-1 (i.e. adding 1.25" track or a better 1" track) that you'll find any aftermarket clutch kit will be better than stock. If the traction issue is not addressed, adding a clutch kit will only make matters worse.
