Sadly yes. In a nut shell, Eibach springs and rear camber kit at 1,000 mi. Had even wear up to 4,500 (when 3/32 was documented) than after tire warranty check Firestone asked to check my alignment which had been checked and reset 6 days prior and my toe was off BAD! Those 6 days showed on the tire as the outside was worn from the tires pretty much dragging. My toe was .40 ish on both side were the factory max is .22. I didn't see the alignment being the culprit until that. Took it to the alignment guy today that Mike's Z shop in Whittier swears by so we will see if the alignment stays. They said my toe bolt and another were loose. Pretty sad when it was re aligned yesterday and my readings were off again so I dumped the shop I've been going to for years. Took it today because it was pulling for the first time, after tire install yesterday. I'm seriously fed up, to be honest. It's a brand new car so I can't imagine anything else being wrong. Frustrated. So the answer to your question (my opinion): bad alignments.
