old cragars and a 72 swinger

Well ummm?

Lets say you got an 8 inch rim if the center of the rime, the part with the holes for the studs was right in the middle 4 inches from ether side then you would have 0 off set. Now lets say it is an 1 3/8 away from the center line of the rim you would have that much off set.

Then there is negitive and positive off set.

If it is off set to the front of the rim it is negitive off set

If it is off set to the rear of the rim it is positive off set.
