Could anyone offer advice on how much the tire size might be increased on the Abarth 17" wheels? I'd like to replace the 205/45R17 Potenzas that came on my Abarth with Pilot Super Sports. I'd like to go up to a 215 and maybe increase the aspect ratio as well. I did this on my Mini JCW with very happy results, but I'm not sure what the Abarth wheel wells and suspension will accommodate. Any thoughts would be much appreciated.
