I have an 02 F-body that I have installed mini tubs in. I have a stock width Moser 9 inch in it. The tubs have opened up alot of room but the spring perch on the moser is going to limit the width of the wheel. I am also running offset Spohn control arms. I plan to run a 29.5X10.5 tire. I also plan to run 15" wheels all the way around. The wheel wells will be roled as wel.

What is the proper rim back spacing for my setup?

Most people run a 7.5" backspace for a stock width rear. If you were narrowed 2" on each side you could go with a 5.5" BS

Most of the 12" rims I like only have a back spacing option of 5.5 or 6.5. I spoke with Wolfe Racing were I got my tubs and they suggest to narrow the rear 3 inches on both sides and run 6.5 back spacing. I called Moser and for 125 bucks they will narrow it, plus 615 to get the new 33 spline axles, bearings, and spool I need for it. So 740 bucks and I am good to go.

Does anyone know were to get some 15x12 wheels with 7.5" back spacing? I would like to look them over before I send this rear end back to moser.

Thanks
