20x10 in wheels on VF SSV ute

[Fat350]

Hi I’m wanting to big brake set up on my ve Ute
I have 20x8.5 front 35offset brakes fit fine
What’s the largest offset I can run on rear without hitting calipers
Currently the rims are 20x10 45 offset and I need 15 spacer which I don’t like
so I want to keep deep dish look I can get 4 x20x10 40 offset but will they scrub out on front

Doesn’t the offset requirement for brake clearance depend on the design of the wheel you’re planning on fitting?
