i have a 94 thunderbird and want to get some rims for it. I was looking at superbuytires and wheelmax at rims and was wondering if 18 chrome or 19 chrome is better. i was looking at adr x factor - does anyone know if this wheel has the corret offset? since the car has 85K plus i want to know if the car should be lowered to fill the gap in the wheel well or what size tires would fill the gap w/18's. also could you lower a car with just springs?
