Feedback on Suspension/Tire Combo for W124

Based on all the searching and researching I've done, this is what I've concluded regarding appropriate setup for my 300E:

1) Sportline sway bars front and rear
2) Stick with stock springs (LarryBible swears by 'em for ride compromise)
3) Bilstein HD front and rear
4) Appropriate bushing, linkage swaps, rubber mounts when doing the above
5) Steering damper

Now I'm committed to a 16x7 inch slk 7 spoke rim (I'd buy from you Luke, but tirerack.com doesn't seem to offer them). The original wheel and tire height for stock 195/65r15 = 24.99". The alternatives for similar height are:

1) 205/55R16 = 24.88"
2) 215/50R16 = 24.47"
3) 215/55R16 = 25.32"
4) 225/50R16 = 24.87"

Option 1 is the obvious choice at first glance. Option 4 is a recipe for rubbing based on previous posts here at the forum. Option 2 is a possibility, but with a 0.5 inch reduction in height, that equates to a 1-2 mph skewing of the speedometer reading at highway speeds (hardly an issue). More importantly however, is that the 0.5" reduction in height makes an already unfilled wheel well look even more empty. What about Option 3? There seem to be mixed reviews on the forum about whether it rubs. If I'm doing the Bilstein HD's, wouldn't I see less articulation of the wheel and therefore less chance of rubbing? Any thoughts? I'm still not sold on Option 3 even if rubbing isn't an issue due to increase in unsprung wheel/tire weight, but I might sacrifice .05 seconds on a 0-60 run in favor of a more filled out wheel well that can be accomplished on stock springs.

All comments are appreciated.
