[W126 Coupe] AMG 3-Piece Rims

[Axel Wulff]

I have been looking for a set of the AMG 3-piece rims for a while and one 
set for sale on ebay made me a little apprehensive.

The set I saw for sale had one rim with a hairline crack at the center hole. 
I checked around a little bit and was told that such a rim would not only be 
unsafe, it cannot be repaired.

To make matters worse; spare parts for these rims are no longer available.

The solution would be to buy extra rims for spares.

Browsing the German ebay, I came across this item.

It is the center section of a 3-piece rim and is listed with an offset/ET of 
30. Which is not the right offset for our cars.

Does anyone know whether it is the center piece that determines the offset, 
and not how is mated to the two other pieces?

Would be useful as a spare part if it doesn't determine the offset/ET. 
Otherwise it would only be an expensive paperweight.

Appreciate your inputs.
