As the season draws to a close, the Chase for the Monster Energy Cup brings us to Phoenix and ISM Raceway for the prelude to the championship finale. This race marks the cut from the Round of 8 of the Chase to the four-driver Championship round at Homestead. We make a big departure from the 1.5-mile intermediate ovals and come to one of the few flat tracks on the circuit. PIR is an irregular "D" shaped oval with very flat banking in the corners of nine to 11 degrees. The straights are completely flat, and very fast as they carry off into the sweeping corners. It is truly a unique facility among those on the Monster Energy Cup circuit, and very fitting that it plays a key role in the Chase for the Monster Energy Cup championship. The Phoenix oval has undergone several changes since the series last visited earlier this year. The laundry list of changes includes the following:
1. Moving of the start/finish line to the area between the former turn 1 and the dogleg, thus flipping the turn numbering.
2. Reconfiguration of pit road including:
A. Moving the pit entrance down the new backstretch (former front straightaway) and the exit to just past the new start / finish line.
B. Extending pit road stalls around the new turn 4 (former turn 1) and to just past the new start/finish line. The majority of the pit stalls will be on a curve and prior to the start/finish line.
