Brake size and caliper color, maybe a list of common brake swaps/kits. And a brake dust feature. Wheels are not always going to be clean. I actually prefer the look of the silver RPF1s covered in brake dust.

Oh and window tint by percentage of light transmission!

Are you doing the modeling yourself or is that a model you found? Pretty accurate and detailed.
