backspacing with weld wheels

I was just wondering what backspacing I would need with weld wheels on the rear.

For 15x8's use 5.5"BS

For 15x10's use 7.5" BS.

You will have to grind the fins off the calipers if you use the Pro-Stars or Drag-Lites.

EDIT: This is a 15x10 7.5"BS Pro-Star, with a 28" QTP:

15x10 7.5" BS Pro Star

The 15.8 5.5" BS will put the outer edge of the tire/wheel in the same location.

I run 7.5" on a 10" wheel. It looks good and tucks up under nicely.
