Do 225/45/17 fronts fit? I've heard 255 rears can cause rubbing issues if running lower than standard ride height, but may depend on a number of factors, including wheel offset, camber, spring rates etc.
Yes.. think mines are ET20 offset

I run 245 on ET20 offset with 110mm ride height and 3 Deg neg camber. Had rubbage inside and outside. Spaced wheel out 5mm and cut arches.
My rears are 9J ET30 - so was trying to work out whether to go with a 245/40 or a 255/40

My rear wheels are 8J ET30, with 245/40/17. No rubbing issues at all, but thats standard ride height using Exige suspension.
Indeed - So i was going to move to a 255/40/17 rear as my rear rims are wider - just trying to work out if it will still be rub free and not cause horrible understeer if the fronts are only 225

...and cut arches.
How? What does this look like and what work is needed?

I think i am the only one on here who can answer this question as I'm sure I am the only one to run these sizes. On the road 225F and 255R do not rub if spaced correctly. I currently run 225 Federal RS-R's on the front and 245 Yoko AD08's on the rear but I ran with a set of Potenza RE070 255's on the rear for a while without issues. The only reason I went for 245's is the clearance on 255's is very small and I thought the extra flex and cornering load of track use on the tyres could cause rubbing issues. It didn't catch in heavy road testing but I never got them on circuit TBH.
Mine must be too low with too much camber as I rubbed inside and out with a 245.
