AMG W204 and W205 wheel offsets

[Theador]

I think this question has been asked a few times but I can’t find one that refers to the offset. In short I’m looking to downgrade from my C63 W205 estate to a C63 W204 estate and wondering if I’ll be able to use my spare set of W205 18” AMG alloys on the W204

The offset on your S205 18" alloys is Front ET38 and Rear ET 56 on 8.5j and 9.5j rims.
An S204 C63 with 182 alloys will have the Front ET45 and a Rear ET54 on 8j and 9j rims.

Using the will they fit.com website calculator this is the difference between the 205 and 204 using the recommended tyre sizes on the alloywheelsdirect.net site.

Compared to your existing wheel, this new wheel will have an inner rim which is 0.7mm closer to the suspension strut. The outer rim will poke out 13.4mm less than before.

Hello

Just further to this thread, I have a W204 C63 estate with the 19 in turbine wheels and I’m wondering if the 19 in wheels used on the W205 C63S will be a direct replacement fit as my wheels are past their best now and are not available new anymore.

Can anyone help me with this please?

Thanks.
