Performance Action Day is a full-throttle celebration of high-performance, modified, and enthusiast-built machines at Castle Combe Circuit — bringing together one of the most electrifying mixes of cars, clubs, and track action anywhere in the Southwest. Designed for drivers and fans who love power, speed, and a passion for engineering, the event transforms the 1.85-mile circuit into a hub of energy, noise, and performance culture. Expect live drifting demonstrations, back-to-back public track sessions, club and individual display areas, a trade village, display competitions, and a full day of fast-paced action both on and off the track.
