ive had mine in for a few months now. it wont chatter at all once you figure out how to drive with it. but yes if you chatter a bit, you'll probably break stock mounts, lucky i swapped in polyurethane ones when i put in the act, but now my tranny mount is broken....
havent heard of any issues with the act wearing out very quickly, but regardless, if you need to hold a lot of power, you dont have any other choices.
there is also the act street clutch... or stock replacements if you dont need it to hold a ton of power. |
