I thought I was quite happy with the 18inch wheels on my e38 7 Series, however, browsing Flea Bay today, I've come across the following. The rims are made by ASA, the model is AR01 (designed by BBS). The rims have the dimensions 9J20 ET18 (front) and 10,5J20 ET26 (rear). The tyres required are 245/40R20Y and 275/35R20Y (speed index up to 300kph)! I believe the car requires no modification to get them to fit, please disregard the garish e38 pictured, its not quite to my taste.
