let me put the flame suit on first...

Ok. So I searched and I did find a thread where it talked about the C450 wheel issues with everyone chiming in on what would work vs what would not. I just want to confirm what the OEM wheel configuration is for example on mine I opted for the 19" black mutispoke wheels.

When I look them up in the MB OEM parts finder (have to us the 450 from 2016 so may these are not correct) it says the following parts numbers and config:

20540113007X21 Front = 19 X 7.5 ET44

20540114007X21 Rear = 19 X 8.5 ET52

is this correct?

I want to get some wheels and basically want to ensure the offset and front width is correct. Dont want to use spacers.

once again excuse the redundant question.

I want to say that is c300 front fitment.

I want to say the c450 front offset is more like 33. But I cannot find where it was reported in my half asses search.

The rears are the same and that is correct.

Those are correct sizes I have the same wheels on my C43. I don't think you will find a direct aftermarket swap doesn't exist to my knowledge. I checked BBS factory rep for example and they can only provide a setup with spacers.

I have my Niche wheels left from C450. Will confirm fitment once my C43C arrives. Production date 01/09/2017, so it should be here in February…
