Ok may have found a set of wheels, Work Emotion Kiwami
18x8.5 +38
18x9.5 +38

Thinking 225/40 on the front, and 255/35 on the rear. 1" drop on lowering springs.

Looks like it will fit based on the charts, now I see cars with +38 with varying amounts of poke... with same wheel size... is this some difference between wheel manufacturers or ??

Will work fine, just a little stretch in the rear.

The amount of poke for any given offset is going to come down to the amount of camber they are running, and how low the car is.

I think you should be able to find several examples of exactly the setup you are asking about.

I'd run the 9.5's all round myself. 8.5's don't have the same face and you can fit 9.5 on springs with a 235 anyway.. so why go 8.5?
