You probably could but its more than likely going to rub. I was the shop yesterday and some guy came by with a crown vic on 22"s and he could barely turn a little more than 1/4th and that was with low pros too.
okay thanks im going with 20's dubs lol //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif and ima higher it by tighting the springs.
20s actually look good on regals. One of the guys here in our local W-body chapter has 20s on a regal, and is also running high 13sec 1/4s with them on the car
when u start putting 22s on car that are before 2000 then u will do some major mods. Some guys go the cheap route and just raise the car til it does not rub. BUt the real was to do is you will have to shave, add spacers, and relocate some things
