hey guys im about to go ahead and buy the DB volk sf-challenges for my 04 6mt coupe blk/blk. I need suggestions on which offsets i should go with. I'm going 19 x 9.5 and 19 x 10.5 in the rear. I want pretty fat lip maybe about 4 inches in the rear. I dont want the tires to rub and end up rolling my fenders etc. Im a noob when it comes to rims and i need help from a veteran in this field. Thanks a lot. - James
