Looks trick!!
Thought about going the racer look with the number 47 on the side, (black numbers, White circular background). Also some sponser stickers would look good.

Blitz
Piper Cams

Pace
Quaife

As for colour schemes thought about Grey, Black Sivler etc to tone the car down a bit
The red might be to much bling for me.
Keep up the good work
