I got them on sale cheaper than a set of Bilsteins. They are little stiffer than stock but again my stock ones had 75k miles and the body was nearly rusted through so my perception may be off. They do seem to keep the rear end more controlled over fast moving bumps.How do you like those shocks? I've got Bilstein's on my 06, and have never regretted that purchase, though occasionally they're borderline too harsh.
Bilstein 5100s are pretty similar but aren't rebuild able however it's doubtful I'd ever bother rebuilding them.
