Centerline Convo Pro, 15X8.5 and 15X4...which backspace?
I am thinking the 15 x 8.5 should use the 5" backspace, bolt circle 5X4 3/4
and the 15 X 4 should use the 1 3/4" backspace, bolt circle 5X4 3/4..
This sound right. Want to not have to grind or use spacers.

5 inches it too small. 5.5 inches which I believe is the largest BS they offer is still too small. The wheel will not be centered in the wheelwell like a stock 8 inch F-body rim. FWIW, a stock 4th gen 8 inch F-body rim varies from 6.25 to 6.75 (depending on the year and style rim).
This means (using the 8.5 rim).at even 5.5 will protrude over ~1.5 inches further then where a stock 8 inch F-body rim sits. It will stick out from the fender area. Some guys use 7.5 inch wide rims which is a pretty darn small rim especially since you can take advantage of your large fender area using a much wider tire.
I see folks wondering whether 45mm or 50mm offset is best...which is ~3/16 of an inch variance. anything over 1 inch is a huge difference.
Another problem with the size rim your considering is I see folks trying to stuff a 26x11.5 ET street or the like on the smaller ~8 inch rim...this is too small and not recommended by the tire manufacture.
Either consider a smaller rim using a narrow slick, resize your axles to accept the BS options they offer or consider another brand rim.
Hope this helps,
Steve
