Rear-wing end plates of the Dallara DW12 Indy car will have a decidedly different look for high-speed oval events at the Indianapolis Motor Speedway and Auto Club Speedway this season.
Dallara, which developed a second set of rear wheel guards to improve speedway performance, will provide them free of charge to teams.
Original rear wheel guards, incorporated into the design of the new car to help blunt wheel-to-wheel and front wing-to-rear wheel contact, will be used at all other tracks.
The components have been tested in both scale model and full size in the wind tunnel at the Auto Research Center in North Carolina in conjunction with IndyCar.
The new rear wing guards are taller, lighter and have a slightly different shape than the sets to be used on the road/street circuits and the oval races at Texas Motor Speedway, Iowa Speedway and the Milwaukee Mile.
