Limited slip differential (Posi)
I have an 01 firebird v6. I am trying to figure out if my car has a posi (LSD) rear end. I have lifted the rear wheels, and spun one of the rear wheels forward, and the opposite one did not move. I spun the same wheel backwards, and the opposite wheel then spun in the opposite direction. ???? I also tried burning out. I accelerated from a stand still, and there were two marks on the pavement. ??? Thx.
