The ride on mine was horrible after I replaced just the shocks with Bilstein HD's and it wasn't until I dropped it with the Eibach Prokits that the ride smoothed out.jjcarr said:Bilsteins generally have very stiff compression damping. I've used them on several cars and never been wild about the ride quality. I find they make the car too sensitive to small bumps. On medium to large bumps, they do well.
Koni's, however, with their adjustable damping, can give a near-stock ride, to track-ready just by turning the knobs. When I replace the shocks on mine, you can bet it will be Koni. I'd love to get the new FSD's, but they don't appear to be available for the w202 yet.
Bilsteins have a slightly better reliability record, but both are good.
