The Leyton House CG901B is tested prior to the Goodwood Festival of Speed 2012. Gary Ward puts the car though it's paces on Sywell Aerodromes hard runway. This is a typical shakedown prior to an event to ensure that all the cars systems are functioning. The test flagged up that the car needed a touch more rear ride-height in its current aero configuration. The fitted rear springs are 3500LB which gives an idea how much downforce this car makes on a smooth surface.
