Years ago i pitted for a guy running a sportsman car on a 1/3 mi clay oval(Chevelle body,tube chassis,stroker SBC)). Last couple weeks of every year were"open" racing(do what ya want with your car and run it) We did a big ol' wing every year. Crazy how those things affect the car! Our driver could flat foot it down the chutes and give the wheel a twitch entering the corner, then just let the wing carry him through...essentially flat footing it around the whole track. Knocked big time off our normal lap times.......they look goofy but TONS of fun!!!
