S63 10-spoke wheel






Front : 20 x 8.5 et 39
> compared to E63S factory setup (20 x 9.5 et 25). -1mm clearance to strut housing . +27mm extended outward
Rear: 20 x 9.5 et 39
> compared to E63S factory setup (20 x 10 et 55). +22mm clearance to strut housing. +10mm extended outward
Therefore, the rear is workable but the front is going to be odd looking due to excess extension of the wheel.

if you are to buy the same rear wheel and put that to the front, then the result would be:
-14mm closer to the strut and +14mm extended outward. Not sure if this is still workable or not. I don’t believe adding spacer is the answer here
