Front Fitment 9.5 et23

Assuming I want to run 255 up front, what’s the min camber? Anyone with actual experience?

I think the offset on the wheel might be too much... I run a 265 front with a 9.5" et30 front wheel and it has a lot of poke.

255 fits really nice with -2.6ish camber. 265 requires a min of -3

Thanks, that’s what I thought but having someone else validate is helpful.

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
