Are Looks Going to Hurt Performance?

[Phly6]

Hey everyone, Christmas is comming and that means stuff for the stang. I have an 03 GT and im looking to upgrade the exterior. I dont think the car looks bad at the moment, but when i look out the window from work and see it sittiing in the back of the parking lot, it just doesnt look as fierce as it actually is. Its not a Cobra but i have blown away just about everything ive raced and i want people to know. I back it in so i am staring at the front from far away and thats what im looking to change as of right now. One of my coworkers has a dodge stealth and is always complaning that my car is ugly and his looks much better. Obviously i know he just doing to bust my chops but after a while i started thinking about it and decided it could look better. Im thinking of a new front thats lower for it and some black racing stripes. Id also like some stickers or something for the side but im not exactly sure what kind. I dont want it to look ricey at all, just fierce. Also id love one of thoes really tall spoilers that are actually for american cars, not imports. Any ideas on colors for stripes? or where i could find the front body kit? Also, my friend told me that if i get a lower front ill have to buy some kind of extension for the intake pipe cause a lot of the airflow comes from underneath and it will be cut down if i get the body kit for the front. This true? Thanks any helpful imput appreciated.
