Hi their i have a fiat 500 with 16's and want to get abarth 17's but have been told that they would rub as im lowered on eibach sportlines, is this true? Where and how bad does it rub?

Thanks Julian

Possibly yes, depends on how wide you're going here's a calculator to try and help you, but you will need to know the original offset

however this applies to a normal set up, so lowering it will decrease the available space quite a bit?

Outside edge is where it tends to rub, can be so bad it wears away all the outside edge, and can give off clouds of smoke going round corners or when loaded up, not what you want.
