Hi - i'm new to this forum and need a bit of advice from you all. My Z4 3.0si coupe sits 10mm lower on the driver's side than the passenger side. Both front and rear on this side are 10mm lower when compared to the passenger side (right hand drive car). I've had the car checked out twice by a main dealer and once by an independant specialist. No springs are broken. The main dealer told me the difference was within their 'tolerance' levels. The car has no damage to the chasis. I have a theory that perhaps one side of the car has had new springs (the car was a BMW demonstrator for 9k before I bought it) - hence a difference in ride height. Any ideas??? Also - as I am thinking of having the springs replaced on one side what should the ride height be (from wheel arch to alloy outer rim). Once side measures 11.5cm front and rear - the other 12.5cm front and rear... A really puzzling one - thanks in advance for any help/guidance :?
