I have a 92 500sl and there are AMG wheels on the vehicle but are in odd configuration. They are all 18" and here are what they are:
8J x 18EH2 with Et of 30 code A2114012102
2 of 8 1/2J x 18H2 with ET of 44 with code of A2204010802
9J x 18EH2 x 18EH2 with ET of 39 with code of A2114012202

They are all mounted on car with 8mm spacers underneath all.
I know they should be 8Js on the front and 9Js on the rear but this is what i have.

IS there any configuration that is best with what is there and should I change or remove or add spacers on any or all wheels?

My first thought would be to put the 8 1/2Js on front and remove the spacers and put the 8J and 9J on the rear and add the 8mm spacer to the 8J and remove the spacer on the 9J.

really struggling with this.. All the tires are 235/45 R18
