SG: While I'm not exactly sure about your question (ie, what you are looking to accomplish), Option Package E3 (the "Sport" package) adds 8x17 5-spoke alloy wheels, 235/45 R17 94W performance tires, aerodynamic sculptured lower body work (side skirts, front air dam and rear valence) and projector beam fog lamps. Mechanicals are the same as the E430. There are a variety of ways to upgrade the suspension, like replacing with AMG spec. pieces or getting components from an outside source.
Hope this helps.
Gary
