Indianapolis Motor Speedway

Indianapolis Motor Speedway requires a O'Reilly Auto Parts Series setup built for straight-line speed, drafting stability, and confidence while running in traffic. Over a run, consistency matters as much as outright lap time, so small balance changes can make a major difference.


These NASCAR 26 setups are intended as starting points and can be adjusted to match driving style, assists, tire wear, race length, and changing track conditions.
