I have been looking through the forum and I see that Swift would probably be the best bet when they come out. They are relatively stiffer than the Nismo rates and they have dynoed both nismo and stock shocks.

On the chassis that I work on, I like running Swift coilover springs, so material and design wise of their coilover springs at least are unbeatable. I haven't used their lowering spring kits so I really can't say anything about them, but it seems to me like they do a good amount of homework before they release anything.

Again its just my opinion and what I'm probably going to do.
