I'm thinking of swapping my 09 LT pie cutter rims for some sportier 09 Malibu rims and tires, (Pic below). The Impala rims look too hub-capish. My impala wheels are 16 inch and the Malibu wheels are 18 inch. Should they go right on without any special modifications? (allignments or anything?) Will there be anything noticably different when driving? Good or bad for the car? Thanks!
