hey, im going just gonna go ahead and replace the diff in my z just because the current one has had enough. i drive a 1970 240z with an 82 zx turbo motor in it, and i don't really know what gear ratio i should go for when i put this new diff in. my friend suggested going for a 4:11, but i've since heard otherwise. any suggestions would be appreciated.

 

yea, thats what i've gathered. at this point i've also heard suggestions for a 3:70 and a 3:56. is there anything that would ultimatley be best?

 

alright, thanks for the help.
