Backspacing help

[Soundmound]

Well I called Custom Offsets finally since no one else could give me a clear answer. They seem to think that the 4.5" BS is the way to go or at least what he would run. It should give just a smidge over 1" clearance with a 255/45/20 and have a little more dish to the wheel face. The 5.25" BS would pull the wheel way in, be flatter and likely need some spacers to look and act right. Guess we'll see when I dry fit one upon arrival...

Hi . I might help just finish with mine and I went with 4.5/6 drop in my squarebody suburban . If you don't have a narrow spindle or narrow A arms you are going to rub . I put 20 x 8.5 with 4.75 bs Halibrand sprints barely clear with my narrow cpp modular spindle and flip kit on the back. I did go 5.5 drop in the front but had to raise it since I rubbed the tub and fender. Hope this helps.

Maybe I should have done the 5.25 BS...

So what’s the verdict on these? I never saw these wheels til today but quickly decided these are the wheels I want on the 77.
Not sure I’ve ever seen a pic of yours. Please post one.
The Mag7 gold color I think goes well with our colors.
Holley is kinda limited in sizes available but found 19s and 20s that will both work in the front and back with my planned 3/4 drop.
Love to see your truck with those wheels.
