Hi-power, I had the same problem you have. I try to get this MAE rims used, 18x8.5 with 245/40/18 on them. I've got my eyes on that rims for a long time, I loved it. But I am not sure, will those rims fits on w124 perfectly. Now, I've been thinking how to get my fender out at the front, I did it by put some thick spacer on the bolds so the fender will stick out more.
man, if you dont mind me asking how much you get that MAE rims for? did they have more?...let me know thanks
