Sonoma Raceway

Sonoma Raceway rewards a balanced O'Reilly Auto Parts Series setup that can brake deep, rotate through technical sections, and stay stable over curbs and elevation changes. 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.
