I just put some Eibachs on my billies on my M3 and I kinda wish the drop was lower to close out the fenders...but I am currently running 235/40/17s so I imagine a 225-245/40/18 would be 1/2" closer to the fender. I want to see this to decide to upgrade to 18s or to put my money in a different suspension setup first.

I dunno if this helps, but here is mine with H&R race and Billies on 18s...

I actually would like to test fit them on my car so looking for someone local. Thank for the pic though. Looks like a nice stance.
