10" front wheels 1st gen Chassisworks subframe

[Mikamaro]

So I know the 10" wheel up front has been done. I'm about to dive into minitubs in the rear and would like to slide my wheels right up to the front. Wheels are 17x10 w/ 5.75" backspace. Anybody know what backspace is optimal for the 10" wheel up front on a CA Chassisworks subframe? Would I have to homemade minitub the front? I don't want to mess with the outer lip at all.

Current wheel up front is 17x8 with I think 4.25"BS. So I would be adding 1/2" towards the lip which might be tight and the rest to the inside.

Advise, pics?

Thanks,
Mike
