I have the original AMG sport package wheels off my 220 S600 I believe they are 8.5 42et, 9 44et. They need to be refinished...when I took them off the car, they drove perfect. The eurotech rims are perfect and chrome. 8.5 44et, 9.5 44et. However they have a vibration at 60mph. The right front has a center bore of 66.8...should be 66.6 Should be a old thread on this site. When I drove in the city, it's hard to notice. Both sets for $700...local pick up only. I live in the Houston area.
