Thanks for the info. In the U.S., the cars come standard with relatively aggressive wheels and tires to begin with (7.5 X 16 alloy wheels and 215-55-16 tires.) I will, however, be going up to at least 17" (and more probably 18" at some point.)

As for the suspension, according to the specs provided in the Mercedes brochure, the E300 Turbodiesel curb weight is 3,640 lbs. The E320 (gasoline) weighs 3,460 lbs.,so the E300 weighs 180 pounds MORE than the gas car, and that weight is directly over the front wheels. ( this is due mostly to the additional weight of the cast iron engine block and turbo system in the diesel vs. the aluminum engine block in the E320.) If I use the springs from the E320 "sport" wersion, (there is no diesel "sport " version available here) those springs are designed for a car whose front end is 180 pounds LIGHTER, hence the heavier car will overly weigh down the springs, the car will ride too low and probably will ride softer than what I have in now.

The other possible option is the suspension from the E 430 Sport which weighs EXACTLY the same as the E300 TD (3,640 lbs), however in the Mercedes brochure, it DOES NOT state that there are any suspension upgrades included in the E 430 package. As written, the sport package includes (and I quote from the brochure) ..."contoured front airdam, side skirts, rear valence, projector beam foglights, and low profile 235-45-17 performance tires..." end quote- There is no mention of upgraded springs, shocks or sway bars.

So essentially I still do not have a definitive answer. Any other ideas out there?
Any ideas Benzmac? Help!
