Yes it will fit. And inner clearance is fine. I have 9.5 et35 front which is 2-3mm from stock struts. Et27 will be around 0.5 inches from stock struts.
Just use 235/35 tyres front
No need to mess with camber unless you want wider tyres to front then its different story.
Here is few samples
19x9.5 et 30 with 235/35 basically the same as et27.
this one has 18x9.5 et27 with 225/40
I know probably not Xi´s , but does it matter isn´t the fitment the same?You only need to try to keep your tyres rolling diameter about the same between front and rear.
