blitz technospeed z1 fitment options

My buddy has about 4 or five sets of these wheels
He thought the rears were 19x10 et22 but we found out bozz performance changed them to a 10.5 inch wheel inside lip to inside lip. they r actually 11 wide outside to outside with about a 6.5 inch backspace. A little less.
Question 1. Woild that deep of a backspace work? I put them on and it was fairly close to the susoension with the susoension drooped down
Option 1 for me is those rears with 19x9 et45 up front which id need a spacer for

Option 2 is 18x9 squared w et45 offset. With this offset for the front would I be able to run a spacer that is a 114.3 to 120 adapter? Are there 15-20 mm adapter spacers

Option 3
18x8.5 et45 front and 18x9 et45 rear
Drive hard so id like to have good looks and not have to drive slow everywhere

The 10.5 wheel is around et26-30. If you don't mind putting some work in that is perfect but it is not a bolt on fitment. You'll need to roll your fenders and trim some metal where the rear bumper and fender meet.

9"et45 will be flush up front with an 18-20mm spacer.

He has a few supras. He was gonna put the 10.5 on his widenody but they were to narrow so he just put them in his closet. He said he wants to make a coffee tsble out of them lol.

He alternates the other sets on his other cars amd has a couple sets collecting dust. I can see if he wants to sell. I think hes letting a friend put the 8.5 on an nsx

This question is probably stupid but I can't figure it out. I measured the centers and they seem the same but does a 18x8.5 et45 center face have the same center face dimensions as a 19x9 et 45. I have 6 wheels here now and want to take the 8.5 et45 centers off the barrels and put them on the other 9" barrels so I can run a square size and rotate wheels.
I have one matching set of 4 faces that are black but are 8.5 and 9" the other 2 wheels are 9" wide with silver faces. So can I put the black faces off the 8.5 onto the 9 and all 4 be the same
