The 6 series has 14mm offset, i.e. the distance from the mounting plate to the center of the wheel. The 5 series has a 20mm offset. Therefore mounting the 6 series wheel will result in the wheel being pushed out by by 6mm.
In a 18 x 8 wheel, the width of the wheel is 8 inches and changing from an offset of 20 to 14 should be O.K because you only push out the wheel by 6mm.
As we know the 5 series sport comes with an 18 x 9 inch wheel with an offset of 20mm. Thus by adding 1 inch in the rear wheel by changing from a 18 x 8 to an 18 x 9 wheel width with the same offset of 20mm you are essentially adding 0.5 inches to the outer and inner side of the wheel on the 545 sport pkg. Now converting inches to mm thats 13mm. So in a car that can take a 13mm extension on either side of the wheel a 6 mm extension should be O.K.
Performance shouldn't change that much but I am not an engineer. Please don't quote me and risk getting the wheels. I am only expressing my deduction of why these wheels should fit. I wanted to get 6 series wheels for my self too.
I have spent more than I can getting my 545i sport, so I can't experiment. But if any one does I would love to see pics. I love the 6 series wheels. :wub:
