I've had silver design for almost 3yrs. First two with Bilstein B6 / H&R sport springs, last year with KW V3's. My ONLY complaint is rapid corrosion in a salt state (Nebraska). This allegedly could have been prevented with a waxoyl-type protectant, but I failed to anticipate this issue. I plan to replace with same silver arms, but with a good protectant barrier.
