Forza is a great place to try out mods if you don't have photoshop (or the skills to use photoshop). It would have been the front you'd have had difficulty with as it won't let you position the plate correctly at the front of the Mk6 GTI.
Heck you could always try out a remap on Forza.

Just whack the power up to around 255-260 and see how you like it.
Unfortunately you can't black your badges out though
