According to Autocar
"The Fiat 500 now has a rear anti-roll bar that is 30 per cent stiffer than the original unit, after the Italian manufacturer adopted the settings developed for the Ford Ka.

The Ford Ka went on sale after the Fiat 500, using the same 500/Panda platform with a Ford-designed body and Ford-tuned mechanicals.

Fiat initially used the Ford developed set-up on its Abarth badged derivatives of the 500, but has subsequently adopted it for standard 500s."

May be worth waiting for if thinking buying new.

ARB has been on 500s since January. Did not have a rear one initially so the 30% figure is suspect.
