i dont think so, you can never have enuff stiff stuff. you can add as much as your back can handle. most people are happy with springs/coilovers for drop, jdm ctr rear sway. and front d2 double X brace. that makes our ep into a big streetable go kart
:) , having that said, i have non of these mods except for springs.. but they are on my mods to come list..
