What specs for a concave wheel?

As the title suggests, I'm looking for round about specs to achieve a concave profile. Preferably mild up front and aggressive out back.

I'm contemplating 20x9.5/10 & 20x10.5/11. I'm unsure about fitments though. My previous experience was putting 20x10.5 & 20x11 Niche Apex on my 5th Gen and they looked phenomenal. Any help would be appreciated. 😂

If it helps, I'm planning on Envizio EFS4's.
