i have some questions for people out there with more knowledge. i have a 2000 civic si. i just got done putting a drag 3 turbo kit. inline pro headgasket and inline pro cam gear to lower compression so i can run on a higher psi with stock internals. although currently i am running 6lbs im driving down to inline pro in virgina so i can get it tuned and run on 12LBS safely. but my question is about axles and tranny's. i put the competition enginering traction bars on my car and poly urethane motor mounts but im still worried about breaking my tranny and possibly the axles? i have already been told that my axles are strong enough to hold well over the horsepower i currently have. does anybody have any recomendations for not breaking axles or messing up my tranny? i get a bit of a shutter when i take off in first gear, not launching etc. just daily driving. im not sure what the noise is? but i dont think its clutch chatter? does this noise have anything to do with my act heavy duty clutch? (4 puck) also i was wondering about my wheels? i have 17 inch excel shu's from wheelmax.com they have kumho 205 40 17's on them now, im not sure how much they weigh but im sure they are quite heavy? i was also told that a heavy wheel can cause an axle to snap especially when drag racing and launching? additionally i was told that if i get a lighter wheel i can have the possiblilty of breaking my tranny because of tire spin and gears stripping? would an LSD help this problem? my major concern is my wheels, either i break the tranny or the axles in theory, so i dont know what to do? thank you for your time

 

I think that your far more likely to break parts somewhere between the tranny and the wheels before you break your tranny.

About the heavy wheels breaking axles, it makes sense, but I think they would have to be really heavy wheels.

Since you have the ACT 4 puck clutch disc which doesn't have a sprung hub, hard launches can put a lot of stress on the drivetrain from shock. So if you don't want to break axles, don't drop-the-clutch too much from high rpm's.
