More on Z3 Body Gaps
The specifications for the Z3 and Z3/M coupe body gaps are generally 5 mm all around. The front bumper is not supposed to be flush with the hood. That is incorrect. In fact, the body lines of the Z3 are supposed to be exactly 5 mm in a straight line... the body gap is part of the styling.
In the rear of the car, on top of the bumper, there should be a buffer stop part on each side to set the gap to the rear quarter panel. It is part number 51311925433.
