I just attended a 928 rally/drive this past weekend. One thing that was brought to my attention was the fact that my 1982 928S (ROW) sits approximately 1 1/2 inches lower than the American market 928s. I've owned the car for about 25 ears and it has always had 2 1/2 to 3" ground clearence. I contacted my local Porsche dealer who told me the Euro versions do indeed ride lower than the American models because the American cars were raised to meet bumper height regulations. Does anyone know what the ride height should be set at for a 1982 European 928S?
