I noticed tonight that on my E93 M3 the right rear is lower than the passenger rear by about two fingers (held vertically). Now I havent really noticed this before, but I was checking my rear tyres for any damage and found this out. The E46 M3 had it as well, apparently it was to balance the weight? Any advice or ideas? Tyre pressure is normal, so im not sure what it could be. I am hoping though that it is normal.
