3000gt or gto rear end into vr4

[bazeng]

Only on the launch?

Is the rear bouncing around at all?

Sorry for all the questions, it is just that it sounds like something else is causing the problem..

it does bounce on launch. takes off fine.

it mainly breaks on launch but i have broken a shaft in 2nd before.

That bounce would be what is killing it imo.

Those wheels would be gripping, free spinning, gripping, free spinning while bouncing and that on/off shock to the shafts is what would cause the most damage.

I had some crappy blow GAB front struts on my vr4 once upon a time and I broke 3 front cv's because of the bounce (your would be rears obviously). I changed the suspension to hotibits all round and with more power, it has never broken.

Try and increase the height of your rear with some springs and see if that makes any difference.

sorry mate didn't see my spelling mistake. i was meant to write that it doesn't bounce.

still running the 3.9.

broken the shafts inside the diff. i've broken a shaft on the outside near the wheel hubs.

i'm running evo1 wheels same diamentions as the standard vr4 wheels i think on 205/60's.

last time i broke the diff, it was more of what didn't i break then what i did break.

Have you thought of haveing your transmission cyrogenicly treated ??
