I'm considering the possibility that while my dealer performed the tire feathering TSB and 4 wheel
alignment they over compensated the rear alignment to correct the front? The reason I'm wondering
is that I have 11,500 miles and my rear tires are worn out, the fronts still look really good - I do
accelerate aggressively every now and then but I haven't done any smokey burnouts - I'm thinking
I'll take the Z somewhere other than the dealer to have the alignment checked and if the rear is
way out then I'll go back to the dealer have them check it and if they come to the same conclusion,
demand new year tires from them ? ? I had the TSB done at 5,000 miles, alignment was found to be
way off although I only had minimal front tire cupping - - Any thoughts or advice appreciated.
