That's kinda what I'm considering doing now after further research. Black coroplast discs attached with zip ties and black duct tape to help keep them in position as well as provide a smoother airflow transition from the tire to the plastic. We'll see how it goes, unless I find a better idea before implementing it. This way seems cheap and good though, and can easily be reverted back to stock in a matter of minutes.
