I have been told that withoutdoing anythingto the Focus you can put up to 22" rims on them, somehow this is hard for me to believe. I have been looking online and the biggest rims I have found a focus sitting on is 18"s. This also makes me believe it cannot be done or it would have been done. I surely cant be the only one to think about putting a focus on dubs. I know if it was tubbed out and maybe lifted it would fit any size rims, but sitting stock with 20"s I figure rims are all you could ride on, so if anyone has tried this or has any input I'm definatly interested.
