Well, since you just said that you wanted opinions and new ideas...
The GT stripes is more of a retro touch, as is the hood scoop. The Roush bumper is definitely more modern and simply doesn't go along with the rest of the car. In my opinion, either 1) ditch the Roush and get the regular bumper back with the Mach 1 chin spoiler, or Cobra bumper, or 2) get wheels and a hood that both aren't more traditional and retro.
Car still looks good either way, just my .02.
