I think it's the same suspension as the Z.. not sure if that is considered "sport" by 05 standards. I would expect something extra maybe from the deesignation of "spot" in 05

I see that the 05 have sport tuned suspension. Do we have it on our 03-04's, I dont remember it saying so?

By the way, whats the simplest, easiest mod we can do to our 03-04 suspensions so that it gets rid of some of that body roll/sway when taking corners sharp/fast?
