I am getting looking into installing a tr224 cam, pacesetter longtubes, and an ls6 intake. I already have gmmg and a lid. My question is with these mods will my rear last. Also, will i need a new clutch. I have a 98 m6 z28.
Thanks a lot.

 

clutch might hold...depends on how it's been driven. really hard to say

as for the rear. guys break them on street tires with bone stock engines. other guys get 200 track passes with h/c and DRs...

there is no cut and dry answer. mine is lasting so far as a street car with 315 DRs behind 400rwhp. but i don't abuse it much

 

Lots of variables. Power, weight, traction, driving style, gears, etc. So, no hard and fast answer. Minus clutch drop starts and/or sticky tires on a prepped surface you will probably be ok.

You can do some preventative things to the 10-bolt that will help ensure that it lasts a long time. Case spreading seems to be the biggest reason that the 10-bolt fails. If you want to hit the major issues, pull out your axles and have the axle tubes welded to the center section. Then, install a TA stud girdle equipped rear cover. That will help hold the 10-bolt together.

Beyond that, look at having your 10-bolt set up with a hand-lapped hardened spacer instead of a crush washer, as this will help preserve your gear lash. This would also be a good time to swap out the gearset for some performance-friendly ratios like 3.73:1 or even 4.11:1.

Finally, make sure you reduce the likelihood of axle wheelhop by tightening up your suspension with some aftermarket lower control arms. An adjustable torque arm is also a plus.

 

depends on how hard your drive, i know it wouldn't hold up if i was driving
