Torque ratings for clutches can be compared to contrast ratios for HD TVs. I would not solely buy a clutch from one manufacturer simply because their torque rating is 10 or 20 ft lb. higher. In my opinion, a clutch that is proven to work well with a company that supports their product is preferred. In general, I have been around cars running ACT clutches the most, and I plan to go that route for my personal vehicle based on the experiences other people have shared. I know a lot of people on the forum run SPEC clutches as well. Good thread and it's always nice to know all the options on the table.
