Personally, I think they do albeit should be left on the new model. They are indeed the right shape for the car and bring out the flame surfacing contours well.
Whatever we think sure there will be 3rd party copies doing the rounds before too long!
Yes they do look. Strange that wheels between the new car and the old car seem to flow and suit each. Yet if you tried Z4 wheels on a Z3, or vice versa, not so convinced they'd suit.
Quite like the new car with the old rims....
Just goes to show what a great looking wheel the 108 really is!
