Late in Fast Friday's practice session, the No. 43 entry of Conor Daly was sitting on pit lane with a rear wing unlike the previously announced 'swan neck' design. After much discussion between the team and INDYCAR officials, Daly ran a few laps with the wing before pitting for the day.
According to Schmidt Peterson Motorsports, it was 'just an option they were exploring'.
Walking Gasoline Alley prior to practice, Daly's garage had what appears to be the same wing mainplane with a camera mount attached rather than the end fences.
