Bit more research done today.
After scouring the internet for a Chlorophyll VE with black wheels, I came across a Sedan with Black Dynastys and instantly decided the wheels have to be Silver.
This eliminated the Versus Talon as they only come in black. I think I was more leaning toward them more so for their price whilst still being able to semi give me the stance look I was after.
Whilst the TSW Bathurst are nice, I'd be paying exactly the same money as the Koyas and they don't quite have enough concave / stance for me.
Koya was originally what I wanted from the start. Absolutely loved the fitment of the HSV's at the start! I was swayed away due to the sizing of their 'concave' and 'deep concave' being wide and me worried about fitment. All of those HSV's ran a 20x10 Front and a 20x11 Rear.
I've been told by the wheel shop whom fitted those HSV's have 'pumped' guards compared to standard SS's and if I wanted them, I would need to change the width and offsets but hard to picture how deep the concave will be on a totally custom offset and I was worried it wouldn't give me the same look.
Came across this Series 1 SS Wagon.
Had a chat with the owner and he elaborated on the wheel specs
Wheels: Koya SF06
Front: 20 x 9.5 +30 (Concave) running 245/35 (slightest of legally allowed stretch)
Rear: 20 x 11 +43 (Deep Concave) running 275/30 (slightest of legally allowed stretch)
Suspension: TEIN Coilovers
Car was later bagged and only then did he have issues with clearance having to heavily pump guards etc.
Prior to that, he said he had to roll the front and rear guards (as would be expected). Given this is a Series I, I'm assuming that's why he had to touch the front. 20 x 9.5" +30 is almost equivalent to 20 x 8.5 +20 (2.7mm less) which I am told by you guys and via the information I've gathered around the forum, will fit.
The 20 x 11 +43 quite obviously clears the hub and the big brakes! It also only pokes 4.7mm more than a 20 x 10 +35. It's the equivalent of a 20 x 10 +30.
Koya also have a video of a VE Ute (NON HSV) running a 20 x 10 front and 20 x 11 rear.
I quite prefer to run a 9.5" front because it means I can still run a 245/35 which I already have and by looking at the Green wagon, I'm happy with how it looks so that's a bonus and no reason to run a 20 x 10. I would probably order a +35 offset instead which is the equivalent of a +23 in a 8.5" wide rim which I'm told works!
My only issue now is deciding if I should run with a 10.5" or 11" Rear. 'Deep Concave' is only available in 10.5 and 11.
+43 is obviously the magic number for the 11" rear! Not sure what offset to run if going with a 10.5" which is going to clear hub/brakes and provide less poke than the 11".
Also need to decide on SF04 (which only comes in 'Silver Painted' face) or SF06 (which comes in Silver Machined).
The only other issue is if the Bilstein B8's and 'Super Low' King combo are going to be firm enough to avoid clearance issues or will I need to go coilovers.
