You going White then dude ?
Why not go for WRX graphics for the mud flaps aswell
Could even get 2 small ones for the front doors like the STI's have (Same place)

 

I'm not quite sure. I like the minimal and clean look. I'm gona copy the sticker on Scooby Bits and photoshop it onto the fog lamp covers and see what it looks like. I'll do the same with the Nuburgring one too.

As for the mud flap stickers, they where on the car when I got it but took them off cos I thought it looked a bit tacky.

There's a chap called stickmeup over on TTS (www.tyneteesscoobies.co.uk) that can do you up some custom stickers if you can't find exactly what you want. He did the Subaru lettering for me on my mudflaps.
