Kevin,
The parts you are looking for can only come from AMG or your dealership. I'm not sure if AMG rolled the fenders on the E55. I know they did roll the fenders on the C36 however so they well could have done the same "trick" on the E55. Maybe someone with the E55 tech introduction book or an owner can let us know there.

Rocky,
The C36 had a slightly lower ride height for the euro market. Have you looked into converting your car to euro spec springs? May be worth a call to AMG or your local dealership. Let me know what you find out...EG

Hope this helps...Lee
