A rear wing or spoiler is super effective at spicing up your Pony's side profile and adding some nice lines and edges to your aggressive Mustang build. While most wings and spoilers are just there for show, a select few can even improve handling performance by increasing the down-force on your 2015-2020 Mustang's rear end, which can keep your Pony better planted during those high-speed track runs.
