The poke should be fine when static or just driving around, I am running 9.5 front, et28 with a 3mm spacer, I had used a 5mm before (effectively making et23) with -2.5 on 245/40 RS4 to clear my KW CS. You will find out just how little room there is though once you start hitting the track. I was rubbing on metal with the 5mm spacer with a fairly significant roll.

I have removed my helpers now which really helps so i moved back to 3mm and make clearance better.

Next time round I am thinking of going 255/35, wider but smaller diameter may change the dynamics
