Have a 2007 CLS 550 w/ standard 18" staggered chrome wheels w/ Michelins. In the market for 20" wheels and need advise from those of you who have been there, done that. My criteria is: I like the deep dish look like the Savinis or comparable w/ big lip, thinking 9" fronts w/ 10-11" wide rears, don't want to sacrifice too much on the ride but know I'll lose some comfort, know I'm looking at $3,000 - $6,000 for a quality wheel & tire package, and want to make sure the pressure sensors still work, and don't want any spacers or funky installation. Probably be looking at a lowering package as well later on to make the car look right. I really appreciate if you folks have any advise to share.
