My dad has a 67 camaro RS that will probably be lowered like 2 inches or so and will have disc brakes all around for sure. He's thinking he wants 18's in the front and 19's in the back. How wide can he go front and back for wheels and tires without tubs or anything? Any advice, help, and or pics would be GREATLY appreciated! Thanks everyone. Also, any wheels with a deep lip out back, probably 5 spoke, that you think would look good post up!
