Hi guys. I have tried adjusting the front suspension height on my 94 348 Spider this afternoon as the previous owner has wound the spring bases right to the top and the car looks and drives like a tractor!. However even with spring compressors fitted both the locking nut and spring base are as tight as hell. There is some corrosion on the tread but it does not seem excessive. I have left the threads to soak in diesel overnight and wanted to check that there are no hidden locking screws or bolts that I may have missed before I go any further. Any help, advise, tips would be appreciated Many Thanks Julian
