Well I'm running 11" with an et23 and they are very flush, so I think you will need to pull the arches, which IMO never look good.
Your probably going to have to run some camber as well. Tyre choice will also come into it.
Well it's finally out of the workshop
I have to say I'm chuffed as nuts with outcome, huge thanks to Dan and all the lads at Stride and Sons for all the work and putting up with me for "4 months"
Anyways a few crappy iphone pics until I get some better ones done.
