Just fitted a set of GME parabolic springs to my 57' S1, and I have a 20mm lean to the drivers side (front and rear), which was there when the original springs were attached. Shocks have been replaced too. I'm aware that extra leafs were installed in the original springs on the drivers side to counter the fuel, driver and steering box, but I suspect something else is causing the lean. All advice and ideas about what I could check is appreciated. Thanks, John
