...but I'm guessing just putting a washer on one of the two big torx bolts holding the back bumper on would fix it. The sides can be adjusted some with the brackets and little screws in the wheel wells. I've had my bumper on and off several times and don't think it would be difficult to correct. Send your pixs to BMWNA-- they would have to be real ignorami to not agree the gap is too sloppy for a BMW. Shame on Spartanburg for letting it go out.
