I'm really happy with the RSD. The damping is excellent and there's still room for stiffer spring rates too. I should've gone with these from the start instead of going with the TEIN Flex years ago with the DB8.It's all good. I heard good things about the Buddy Clubs. My friend is looking to get an S2000 and I'm trying to convince him to stay away from knock off and junk parts. Been reading about those coils on s2ki.com and many people like them.
