I've been researching and some say the Sport model has the same suspension as the basic. Anyone know for sure. It would make my decision much easier. Bilsteins basic E430 shock= about $85 while they(Bilstein) lists a shock for "sport suspension" and those are>$150 each. This is confusing because the online dealer where I get most of my parts sells Sachs(OEM) and Bilstein but specifically states "not for Sport suspension" on the E430. Our sponsor here doesn't state anything about sport model/suspension.
