As above no issues with that, ET is spot on.
Great thats good to hear. What size were your alloys/offset callum? You had alot of messing about to get them on didn't you?
So another thing to add to the list of getting some new wheels 
Mine were 16 x 8j ET25, but I am running 15mm spacers on the front to clear the calipers so are ET10. Rolled front arches flat and cambered in and they fit well with no rubbing. On the rear I just cut the lip of the arch off lol.
You shouldn't need to do anything to yours, especially if you get the right sized tyres. 195/40/16 or 195/45/16 should be good on 7.5j.
