I have the sport package on my sedan. I was looking at getting the 350Z H-tein Springs to drop my car slightly and get a better preformance spring. I believe the 350Z H-tein are running 390(front) and 400(rear) while the sport package that I got is running 314(front) and 342(rear). How much would this effect my ride? Also would I have to change out my sport shocks? Please post your commnets.

I am also looking at putting on Stillen sway bars and gtspec bars too.
