What offset wheels??? Aw11

Hi all, just wondering what wheel and tyre combos you can run to get flush with the guard fitment!
I'm heading toward 15X8's and from searching the net I've found two different offsets:
15X8 +23 &
15X8 +35
I'm not sure if +23 is too much out the guards, i don't want to run flares so whatever sits flush with stock guards is fine!
Tyres are the other concern, I have a stock height aw11 at the moment but it will get coilovers soon, scrubbing may become an issue so any help would be greatly appreciated cheers.

I ran 15x8 +25 all round 195/50's. Front was awesome, rear was too but would suit fatter tread as mentioned. No guard rolling either. Rubbed only up front on big dips. Nice cheap lip would've solved that. +23 is close enough :)
