The Abarth-alloys won't automaticaly fit the Uno (if from a Ritmo / Strada). The Ritmo / Strada alloys have another "pressing" (I don't know the english word for it) making them scrape on the inside. You have to use spacers, which are not allowed in Norway. This was for information only, I don't know if it was helpful. (The usual iron wheels of the Ritmo fits though, but they are even uglier than the Unos.)
