I have 22`s (22x9 front, 22x10.5 rear) I rarely have rubbing issues, occasionally when bottoming out on dips at high speeds or the angled entry into a shopping center If i have a passenger I get a slight rub but nothing that would warrant any modifications.
As Yorgi stated, getting your fenders rolled may be an option, I will do mine once I lower it. what size tire are you running? I have 255/30/22 front and 295/25/22 in the rear if that helps.
