I got my K-sports for 695 shipped plus 50 bucks for 9k springs (Extra) so now I can run 7/5 or 9/7 or 9/5 all for 745 shipped. I really like them they are hella low and drive a million times better than strut spring.
The only thing is I dont really know how to properly adjust them. I have the fronts on 50% and the backs on 25% stiff. Its better than full soft but I think if I knew what I was doing they could ride extremely nice.
Another this is my tires bounce a lot. To tall of sidewall, when I push down on my bumper the tire compress's as much as the spring.
