The wheels were not aggressive enough looking being just plain silver.
Tamiya Semi Gloss Black was brushed on to accent the centers and the bead of the rim was brushed Tamiya Red. A clear gloss coat was airbrushed over that.
The tread of the tires were scuffed with some 320 grit dry sandpaper before mounting them on the rims.
The hub caps were decaled with SMS Plain weave C/F #1420 and a custom Scale-Master decal was made for the center logo on each cap.
