Race Car Aero Mockup

Trying to figure out how to design some simple aerodynamic bits for my little circuit touring hatch so I figured I'd do a mockup in Photoshop.

Nothing fancy just an front splitter + underbody panel and some aluminium sideskirts/side diffuser.

Honestly its a crapshoot but hey gives the car a menacing look anyway. Plus more space for sponsor stickers.
