The 30-minute session will take place immediately before the last training session. In it, nine drivers try to “clean up” the surface of the track and create extra grip around the 1.25-mile track, which will host the final oval race of the season on Saturday night.

It’s an idea IndyCar experimented with at March’s race at Texas Motor Speedway, running seven cars on a higher groove, and one that most drivers agree made a difference, even on the PJ1 TrackBite surfaces that helped NASCAR racing but were treacherous in IndyCar.

Therefore, a similar effort will be made for the Bommarito 500 at World Wide Technology Raceway. While he didn’t have the same issues with the track coverage, having a high line in play from the start of the race and then available throughout the race can only increase the passing opportunities.

The session features Alexander Rossi (Andretti Autosport-Honda), Felix Rosenquist (Arrow McLaren SP-Chevrolet), Scott Dixon (Chip Ganassi Racing-Honda), Takuma Sato (Dale Coyne Racing w/RWR-Honda), Connor Daly (Ed Carpenter Racing-Chevrolet), Callum Ilott (Juncos-Hollinger Racing-Chevrolet), Simon Pagenot (Meyer Shank Racing-Honda), Jack Harvey (Rahal Letterman Lanigan Racing-Honda) and Will Power (Team Penske-Chevrolet). The only team not represented is AJ Foyt Racing.

Each car will be given one extra set of Firestones for that session, which will be returned at the end of the half hour. In 15 minutes, the final one-hour practice session for all cars will begin.
