speed demon... don't listen to these folks... it is your car, not theirs. You have the option of putting whatever additions you want on it.. Most of the people here are old fogies anyway. If you are going to put additions on a car, you should put them on this car NOT a civic. Why would you spruce up a crappy car and not spruce up a sweet ride. I am actually thinking about putting the undercarriage lighting on mine - phantom black with a nice low green or red glow would look pretty sweet in my opinion.
Uhh, if you put those on, I'm gonna hunt you down, steal your GTO and report you to the proper authorities in the Renassance (sp?) Center in Detroit so as to never let you purchase another GM vehicle again.
tails by that same theory I could say that undercarriage lighting excites molecules underneath the car providing lift negating some of the weight of the car and therfore affecting thrust in a positive way
