3 1/2" backspacing
I'm a fan of the old steel wheel.
The ring painted a different color than the wheel would be good.
Also if 2" backspacing was available I think you would sell more. Everyone on PBB is fighting to find those and settling for 2.5" BS from 4WP.
As for the design of the ring, I think it should come in towards the center of the wheel more, maybe an inch.
Your target price for each wheel is also what I got all 5 of my wheels for.
