For starters, I do not have any wheel fittments that would be correct or not, with or without a spacer, or anything of the sort that is going to make a 225/50/16 work right on an E 28 chassis car without rolling the rear fender. I don't suggest that you play with offset by using spacers, if the wheels would have worked better in a diffrent offset, we would have them build the wheel that way. The offsets on the type C and M are et 40, where the Emotion is an et 20. they are both correct fittments and will work fine with no mods other than the rear fender. If you you have any other questions, of if you want me to put it together for you, feel free to call me DIRECT @ 800.428.8355 x395, thanks Aaron
