My 2000 M5 rides nicely, but I'd like a somewhat firmer ride with less lean on hard cornering. I asked the high-end European repair guy in town about the Bilstein coil-over package. He told me the ride is adjustable: "Harsh...and harsher." I don't want a harsh ride, just a firmer ride. Anyone here have experience with the Bilstein package? Other suggestions? Thanks!
