I noticed the other day cleaning my car that the rear passenger side tire is about a 1/2 inch to inch lower that the drivers side when looking at the wheel well distance to top of tire (the pavement is even). I have read posts on subframe damage but mine seems to be alright... im riding on 18's but suspension is stock... havent noticed driving difference... but it might be pulling slightly to the right (passenger side). Any ideas on what this can be before i take it to the dealer. Im at school about 200 miles from global imports where i like to take it and the BMW dealer here Taylor reminds me of a ford dealership... so bootleg. Im out of normal warranty but have an extended one... Thanks... my participation in this board has really decrease since dental school started but i neeed to get back into it!
