great thanks, will have a proper look through. It did say the setup was for an s2/3...is it different for an s1 do you happen to know?
Thanks
I don't think the stance was substantially different between S1 and S2/3, but their spring rates may have been. The early S1 cars were principally aimed at town driving and to satisfy the new female market. If you have new (non-original stock) springs, their profile and rate may also be different from standard. The usual method is to loosen the silent-blocks that locate the springs and put some weight in the boot, until the gap between the bump stop and the spring is at the correct value (see workshop manual for your car) - or the stance looks about right - and then retighten. If that takes more than 2 medium adults in the boot, then the springs may be too strong and the silent-blocks could tear after retightening. Hopefully, if new springs have been fitted then any remaining 50-year old silent-blocks have also been replaced.
As for tyres & wheels, I would use the Lancia Instruction Book recommendations for size for the S1 1.3 Rallye. Lancia put a lot of effort into designing the cars as a package. If your wheels are original, they will have been designed to be used with tubed tyres and I would stick with that. It was only after about 1970 that tubeless tyres were introduced and, with more experience, wheels for tubeless tyres were modified with 2 additional safety ridges (inboard of the rims) to retain the tyres in the event of a side impact. If you have a modern replacement wheel which has these ridges, you should
not use tubes - the pressure of the safety ridges can cause localised heating of the tube and failure. There is some good information here:
