I have a limited slip disc brake rear end out of a 91 Z28 and when I turn to the right and floor it, only the right tire spins but when I turn left they both spin. Also when I go strait or power brake it they both spin. I just don't understand why it only spins the right tire when I turn to the right.
Thanks!

Change the fluid and add some limited slip additive and see if that helps at all.

do I have to change the rear end fluid or can I just add the limited slip additive? My rear end fluid really isn't that old maybe 5-6 Months. Also where can I get limited slip additive?
Thanks!

it's really hard on rear ends for you to do burn outs while turning. i'd change the lube and add the posi additive.

OK... but explain this...

I have the stock 3.23 in my 89 IROC and I can pretty much only get two tires spinning if I am power breaking with the 700R4 shifter in "2" or "D." If I do it in "1" or "OD" it only spins one tire.

Can anyone explain this???

Get the limited slip additive at your GM Dealer. It costs about $10. Use only the GM additive, because its the one that works the best.
