During a race this car was damaged in the rear. We fixed the damage and are making a custom fit tonneau cover for the car to help aerodynamics on the track. The cover needs to be both strong and allow easy access. It also fits around all the roll cage tubing. Note the clear window so the driver can view his equipment from the seat. At Triumph Rescue we can make items to fit all your custom requirements. See more images here: http://triumphrescue.com/index.php/gallery/projects/stockton-racing/tr4-race-car-1-604.html
