Honestly, I'd do white if I were you. The storm trooper theme would look good now, but if/when you decide to do a different theme with different wheels, the black spoiler is going to be mismatched. It greatly limits your colour scheme options.
With a white spoiler, you can continue to do any theme you want and it won't look out of place.
