Ontario Motor Speedway Decal

Ontario Motor Speedway was California’s answer to Indianapolis — a massive, multipurpose oval with a road course built into the infield. Opened in 1970 and closed just over a decade later, it was state-of-the-art for its time and briefly hosted IndyCar, NASCAR, and Formula 5000. This precision-cut vinyl sticker outlines the iconic oval.
