I've never seen a 7 1/4 wide factory wheel on a MB car. So let's assume
it's 7.5" which is relatively common. That would mean it's 38.1mm wider
than Carat alloys. Meaning they will stick out 19.05mm in and out. With the
ET51 off adding 21mm on the inside compared the factory alloys, you're now
40.05mm further inward. No go. So then you start to look at spacers to make
them fit. A proper 40mm spacer will be expensive. Something in the
neighborhood of $350-$400. That's not a wise investment, IMHO. You would be
better off spending that money on something which fits better to begin with.
