I was told that my 350Z needs a one time four wheel alignment to change the 'toe in'; required because the original set-up was designed more for racing; improve ride; quiter; safer for normal highway driving; True?
Advanced Wheel Alignment on 2006 Nissan 350Z

Tire cupping is a problem with these cars. Check the TSB. There's a class action law suit with older models. It happened to our 2007 with 17,000 miles on it. Dealer was no help.
