I have helped to install and driven in numerous S550s with these springs, and if you want a stock-like ride quality but improved handling using stock dampers, these are the spring to get. Misinformation perpetuated by the competition on forums will make you feel nervous about having a progressive spring, but the fact is numerous supercars and even race cars use progressive or dual rate springs. You will not be disappointed with these springs. The alternative from the competition, that taught a "superior" linear spring rate is a nice set of springs, but simply can't offer the ride quality and handling mix that these springs can offer. I know this because I've been in cars with the competition's spring, too. Nice ride, nice handling, but I liked these Steeda Progressive springs much more.
Great product with excellent ride quality!
