Waterford Hills' eighth open track day of the season gives you a full day to push your car on their technical 1.5-mile road course. Bring any street-legal or track-prepped car and run as many sessions as you want—perfect for tuners dialing in suspension or drivers building seat time before winter. The Clarkston circuit rewards smooth inputs with its mix of tight corners and elevation changes. Full details & registration: https://www.motorsportreg.com/events/waterford-hills-otd-8-418982
