Separate specifications for superspeedway and road/street/short ovals
Superspeedway-specific aerodynamic bodywork, featuring rear-wheel guards that have a slightly different shape than the sets being used on the road/street circuits and the oval races at Texas Motor Speedway, Iowa Speedway and the Milwaukee Mile.
Aero kit to be used at the 2.5-mile oval for the Indianapolis 500 and at the 2-mile Auto Club Speedway
The rear wheel guard was designed to reduce wheel-to-wheel contact.
The rear-wheel guard/wings work in combination with the other bodywork to create less drag and more downforce.
