Can I get a 9" rear w/discs made to any width. Do they come on the 1/2". The way I have it figured, I'm going to need one with a wms of 58". I wanted to use Billet Vintique magnum 500 wheels 17 x 8 W/ 4 1/2" backspace Tires: 245/45/17 This should make the tire 3/4" from the spring (stock placement) And 3/4" from the inner lip of rear fender. Tire height shoul be around 25 3/4 Does all of this appear to be correct?
I would buy the tires and wheels first and mount them on the car. Then you can see how much you need to widen the rear.
