[W126 Coupe] AMG 3-Piece Rims

[Sharan Bains]

Hi Axel,

On those 3-piece rims (and indeed any multi-piece rim),  it is the centre 
piece that determines the offset.

The outer rim (which is the thin highly polished deep dish) is what 
determines the width of the wheel. You can change the width of these 3-piece 
wheels by simply changing the outer rims. That's how they become 8.5J, 10J 
and 12J (which was an option on the widebody).

The inner rim, which is the fat inner section of the wheel and what the 
centre piece sits in, is exactly the same dimensions on all these OZ 3-piece 
wheels. There is no differnece between the inner rim on a 10J and a 8.5J 
wheel. So when you split them, you don't have to worry about getting these 
right - it's the outer rims and centre pieces you have to match up, i.e. the 
lower offset centre piece must go with the deeper dish on the rear 10J 
wheel.

ET18 is what's needed for the front 8.5's and ET17 for the rear 10's.

ET30 was for the 8.5J's on the widebody w124 AMG versions.
