Yes, the kind of springs you get matters a great deal......avoid aerospeed, apc, pilot, any cheap parts or cheap coilovers. Shocks only compliment the springs, crappy springs with even the best shocks is gonna be a bad ride, and then you have eventual sagging problems from cheap springs, things like that. Koni yellows are the best shocks made, followed up by tokico illuminas (which are much better than KYB in my opinion)....having the adjustability is nice, but I can honestly say I have only adjusted my illuminas ONCE since I got them, and it's been close to six months now. But it is nice to have the option, but certainly not neccessary.
