Re: 155 wheels.. need advice
Most wheels that are made for after-market have a large centre bore, so you can then sleeve it down with a spigot ring of the correct size.
The spigot ring is usually 4 or 5 mm thick and it reduces the inside bore hole of the wheel to the correct size for the car. You can get spigot rings in different sizes from most wheel sellers.
The 155 is supposed to have a centre bore of 58.6mm I think. Most newer Fiat wheels (and Alfas) have a 58.1mm bore.
That 0.5mm of diameter is negligible.. so you could say any Fiat wheels with a "58mm" centre bore will fit.
If you have a 60mm-plus bore in the wheel, use a spigot ring to sleeve the bore down to 58mm (spigot is usually soft alloy or plastic, so fairly "flexible") and if your centre bore is miles too small (56mm etc) then it's possible to have someone bore out the centre to 58mm to a depth enough to clear your hub.
