I'm new to RWD and I wonder if any of you have ever come across this. I'll try to explain. Sometimes when I press quite firmly on the gas pedal, the rear wheels seem to slip (slight fishtail feeling), but, they do not squeal at all, it almost seems like there is some other component slipping (LSD maybe?). Do you think this could have something to do the the rear axel TSB? BTW, TSC is OFF, I have stock 18" and 5AT. Thanks for your help.

 

It's called torque my friend and lots of it. The Z is a torque monster and if you cram on the gas it's bound to slip, squeal and all sorts of other fun stuff associated with power.

 

is tcs off? the description sounds kinda like when it kicks in.

doh! just re-read.
