right now i have eibach prokit springs, monroe replacement shocks(slightly stiffer than stock), mmis(not installed yet), k&n typhoon(not install, but it needs a new filter and probably a new throttle body tube too), and im getting a new clutch for it for now. im thinking about getting an obx header and a nismo catback(by chrismas). outside of that i think i'll keep the car stock, but im thinking about getting some lighter 17s(koya rs-gt im not sure if they are lighter but more durable is what i should say). does that mean i'll run in sts/stx? im not really sure, but im pretty sure whatever the class is, i'll most likely get killed because of 2nd gear topping out at 50mph. thanks for the info.
