hey guys. brand new to the forum, and just wondering what all needs to be done to fit rims bigger than 22s on an 07 impala lt. i already have 22s on it, and they fit like a glove. no rubbing, no poking. but now i want bigger... lets just say 30's... to make it look like a donkey whip. lift? fender roll? probably even drop the axel? i know raw v6 power probably wont even push them, and the gas mileage is gonna be aweful, but that's fine. please help. thanks.
