Enjoy your car man... The 2.5i's are pretty fun, and the fourth gens are good lookin' cars.
As for the hoodscoop... if you like the looks of it - i would look for a replacement hood and do it right (check junk yards for rear end totals)... As for the lip kits, and all that jazz - to each their own. However.... I would ask that you consider not altering the light output of your tails or headlights... Looking good and being functional are two different things. You dont want to increase your odds of getting into an accident for a purely aesthetic reason. In addition, i dont want you
to increase my odds of causing me or my family harm...
Sway bars are typically my only performance related recommendation to the 2.5i guys... Really helps with handling performance... And thats only if you push your 2.5i or are a enthusiast who craves the better feel. Anything performance wise above and beyond that... you likely bought the wrong car
