So I want to a wider mean stance for my rear. Right now I am running a hub centric rings on all 4 tires. Rims have a OD of 72mm stock is 66.56mm

I am at a offset at 40 in the rears.

Do I need hub centric spacers to do this properly? If so whats my best fit to get the centerbore back at stock and my offset back to stock? Whats the best place to order from?

America's tire said they are highly against any kind of spacers, but i want a more wider stance like I had at stock.

TIA.
