Offset spring hangers and shackles....

Not to get into a pissing contest ( plus I’m heading out the door to the Social Distortion show) but most drag radials are good mounted on 10 inch wheels...

That’s fine if you just want to run drag radials I guess. I just assumed he actually wanted to run street tires.

And either way the quarter clearance would be better on a slightly narrower rim. Depending on the actual dimensions of the OP’s factory wheel tubs he might need that extra little bit of clearance.
