Hey guys I have a 98 z28

Was wondering why my car was only spinning one tire when I was doing a burnout with TC off.

Is the diff open or LSD?

its supposed to be a LSD but might have been changed or posi unit is toast

Posi is toast, the factory posi is pretty weak....one would have to be on crack to put a open diff in a Z-28

On the positive side, it's a good time to put some gears in it with the new posi install....or even better, use this opportunity to upgrade to stronger rear end.

Was going to throw in 3.73s
How much would the new posi cost me?

Cost varies depending on what unit you choose. If you are trying to do this on the cheap you could possibly pick one up used.

This question doesn't really belong in the Internal sections, so I'll move this to a more appropriate one. Please pay attention next time.
