Something wierd just happened....Brought my bud on a test drive and did a little burn out...TWO TIRE MARKS (I have POSI) but as I left his house I did an EXTENSIVE BURN OUT and only ONE TIRE MARK (Passenger side). I called my bud up and he said that the driver side tire was not even spinning. Is this a sign of POSI wear in the rear or is there some thing in the rear that locks up as soon as you go forward ( I backed out of his driveway and crawled forward about 2 feet before the ONE TIRE DISPLAY...)????? Maybe the car has to go forward a certain footage until the posi locks up????

Gimme some input
