Re: Anybody change the side Viper emblyms?
I'm guessing that you mean the side/fender lettering.
Use a blow dryer to heat up the letters first, and use dental floss to get behind them, pulling across to break the adhesive seal. Make sure that you carefully measure the proper placement and angles of the current lettering to get the new lettering on straight. Usually the makers of lettering replacement provide a template, but it's smart to be thorough as it's difficult to reposition them once down.
I think that red will really stand out against the black.
