I agree that the DeLorean door design is excellent as it is. Hydraulics or pneumatics would not be an improvement. Often DeLoreans with chronic drooping doors need a torsion bar adjustment. Remember, many cars have had door guides, stronger window actuators, beefier lock solenoids, and other parts added to their doors since they left the factory. These added weight, and without a torsion bar adjustment it will automatically cause the doors to droop. My personal suspicion is that many DeLoreans have had their doors modified without an appropriate torsion bars adjustment to accomodate the extra weight. I know that mine is one of them. - Mike Substelny VIN 1280, 7 years, slight droop on cold days
