wheels
The issue is that the wheels have to run freely in the wheel houses at any angle of steering PLUS the springs/shocks at their lowest position, and the top of the tires stay inside the wheel houses when going straight. Better ask your mechanic for additional details.
Especially the 4-matic is very sensitive on tire/rim dimensions, since the 4-matic control is based on rpm of the wheels.




i forgot to ask my original question. Will the stock wheels from my dad's S430 be compatible with my car?
I have a set of Monoblock replicas intended for snow duty until I traded the car. This is nice size because the original monoblocks do not come in 16.
