I just finished up installing BMR Springs on my personal S550. Needless to say, they are springs that I spec'd out....based on my own car. Imagine that! 
We put in:
Front: SP089 "Minimal Drop" Springs (170lb/in)
Rear: SP088 "Drag" Springs (800lb/in)
This is basically a Performance front spring, with a little less drop than our other Performance Springs....and our rear 1/2" Drop Drag Springs.
I knew from day one that I wanted to have a combination of springs that work well on S550's that add weight to the front end via poweradders....and I think I nailed it.
Car drives amazing! IMO, it looks amazing too.
The wheels are from American Muscle.
20x8.5 Front with 5mm spacers
19x10 Rear
