What backspacing and tire size would work with a 4/6 or 5/7 drop. I want as wide a wheel as possible.
I noticed somewhere, someone narrowed there rearend. but I cant remember how much. I would like to do the same and possibly run 22x12 rears or wider or 22x10 with a hell of a lip. What do you guys think?

 

The lowest you can go with a 4/6 will be with 22's! I would with a 22x10 at the rear with 285/35/22 tire's and with a 265/35/22 up front. With the 5/7 drop no bigger than 20's. A guy I know has a 5/7 on his 99 RC with 20x10's with 295/40's and 20x8's wrapped on 245/35's. Said it rode just like stock and was more than happy with it.

 

I saw the truck with the narrowed rear end, it was on the cover of truckin a while back, it was pretty sick lookin cause the lip on the rear wheels was like 6"! It's gonna be hard to get a 10" wide wheel up front if u want a lip on it and be able to go that low...the fronts can be tricky cause there are so many variables with the steering and such.

 

A 4/6 with 22s is enough work, 5/7 wouldn't be an option unless you really want to cut your truck up.

 

what kind of cutting are we talking about. I was wanting to tub and cut the inner fenderwells but I dont know where to cut.

 

5/7 and 22s wont work very well. only unless you are willing to really **** up you front fenders. the tires will hit when you turn all the time. When I had a 4/6 i had a little trouble turning and hitting.

 

Where will the tires hit? And what will you have to cut?

 

Tires will hit the fender, not the inner fender that you could tub, but the outside of the fender.

 

I would still like to tub the inner fenders. Where do I cut and where does the fusebox, master cylinder, and windshield washer fluid tank go. I can move the battery under the rear seat. I wanted to do this to avoid any future problems and if I decide to lay frame.

 

twanky will be able to help you more than I since his is bagged and already tubbed for the 22s.
