E89 wheel fitment
I currently have a '12 Z4 35i on order and was evaluating my current inventory of winter wheels. I've determined the Rial 17x8 wheels on my current E90 probably won't fit the E89 given the offset issue on the rears. All 4 are 17x8 ET30.
I also have a set of 18x8 M6 replica wheels laying around and wanted to know if these would fit. All 4 are 18x8 ET34. If I understand correctly, they will fit perfectly on the rear, but the fronts will sit 5mm inward. Does that mean I would simply need 5mm spacers on the fronts?
OEMs on the Z4 should be 18x8 ET29 (front) and 18x8.5 ET40 (rear). Feel free to correct me if I'm wrong.
