Staggered setup compatible with C300 4matic
Yes, you can put the same size/offset of the staggered setup from the C300/C400 sport on your car. The C450 and C63 setups must be different in offsets/widths due to suspension arm and fender width differences.
Specifically, I think your C300 will take any of the following:
18x8.5 with an offset of 45 on the front and 18x9.5 offset 45 on the rear.
19x8.5 with an offset of 45 on the front and 19x9.5 offset 45 on the rear.
20x8.5 with an offset of 45 on the front and 20x9.5 offset 45 or 20x10 offset 50 on the rear
The offset can vary by a few mm here and there and still work. You have to sort out the correct tires for each application
There's a handy calculator at www.1010tire.com that lets you play around with various wheel, tire and sidewall ratios and reports back the exact rolling diameter variance. Or just go with the OEM values. You know those are safe.
