Those look like Rota Grids. 
Peoples with flares usually run 15x8 ET0... Without flares 15x8 +25, so probably a 25mm spacer with the 25mm
offset. 
Never knew what tyres they run so this is good reference.
I love the flares, not sure if I can cut the metal work to do it properly though.

Ken's car runs high spring rates and no sway bars (because of the spring rates it is not needed in his setup) i don't think he runs spacers on the street setup (the larger 949 racing wheels with 275 wide tyres did though)

Hahahahahahahaha....hahaha....haha..ha..

Probably 15x8 ET0 then.

That's perfect.  You'll be needing a half-dub next . . .  that's the back half of an AW turned into a trailer.

As cool as it would be towing around a half dub, it's just too big / heavy for my plans.
I want to make a trailer similar to this:

 
But with space for 5 rims/tires, a lock up tool box for tools, parts and an esky (to keep hydration fluids cold for those hot days) and a 12v compressor + tank for doing tire pressures, plus a spare battery for running some port-a-lights, jump starting and running the compressor. Want to try to keep it all under 150kg so it won't be too much of a burden on the AW11 when towing.

^That is just pure ingenuity! But 1.6L will that struggle?

TBH I never bothered to weight the AW trailers.  The tow car didn't seem to have too much hassle pulling it, with a set of tracktyres, toolbox etc.,
 
And the WayCool factor certainly helps . . .

Where did you get that from?
 
I wouldn't mind one as well so I could get a few loads of mulch and plants for the garden in a box trailer.
