first, don't put the screen name on the car, do something more general.
second, the satin black ones look too bland on your car, if they were cut the way the dick harrell's are, might help. along with being broken up by a different color with lettering, might pull it off. chris's car pulls them off nicely though, its very contrasting.
third, i love your hockey stripes. car looks naked without them.
something i'd experiment with, running the dick harrell style with something that runs across the spoiler, just curious how that would look.
your car though so do what you want, and make a white "PULL OFF" vinyl for the top of my tail light
