YEah, I agree w/ Dori Dori. Tie rods, t/c bushings, rear multi link bushings, ball joints (my next step) are all good. Also, as far as shocks/springs/top mounts go I would say best bang for your buck are Nismo S-Tune coilovers. Non adjustable, but replace everything and are designed by the guys that designed our cars. And when compared to the price of AGX shocks, new top mounts, and drop springs, they are about the same price.

Also, tires are good. I am running crappy old tires on my rear for drifting, and Falken Azenis on the front. Also, look into a VLSD.
