Hi gs-racer! Thanks for those tips! big help :) Your seals look just a little different from the ones in my front shock (see pics in the end)... Im wondering if they are the same model because i read somewhere that the GS160/SS180 had two different type of shock absorber - that had differences in the type of sealing... I really dont know any details and am just wondering... Anyway, what you did to you front shock sounds great! You replaced all the rubber seals and changes the type of oil. I read here (http://www.scooterlounge.com/vespa/repair-guides/gs_shock_rebuild.shtml) that the oil should be "seal swell oil" so not to damage the original rubber seals... but I guess if we change all the seals they will the kind of rubberl that works good with regular fork oil for motorcycles, right? Do you still have that extra set of seals with you? Send me a private message and maybe we can arrange a deal... Im sure I can find the Orings around here but if it worked for your shock, it should work for mine (By the way, what is a "radial seal ring" ??... ;) About the 2 springs - I talked with a guy from a shock absorber shop and he told me that some shocks had 2 springs! And that was very new to me because I was really convinced that it had been a bad fix in the past... Now I'm completely confused... Furthermore, I cannot find any reference to two springs in a GS160/SS180 front shock in the internet or in any manuals... Thank you!
