I love my Bilstein HD shocks on the SDL. On a heavy car, they are the way to go. The ride is still Mercedes like (not Caddy wallowing, but not too harsh) and the handling is great. I would put them on an SEC in a heartbeat. I think Dee8go has them on his SEC and I am sure Johnhef has them on his. Ask them for input.
