I'm putting 20s on my 03 coupe. They are 20x9 front and 20x10.5 rear. I already have the tires they are 245 30 front and 295 25 rear. I need to know what offset to go with before I buy the wheels. They don't have to be flush, I just don't want them to stick out from under the car and rub. I know this question has been asked a lot but I haven't seen anyone with this exact setup. So any help would be appreciated. I don't have brembos by the way.
