Daniel, Yes, and Ive asked about getting material removed from the hub face of a rim to make it suitable for a 1600 in the past, and I was told not to do it because the wheel nut inserts are put into a certain depth so removing material from the hub surface would alter how much the nuts are holding the wheel on by. From my previous post it would seem that to get a 7in rim under standard guards (and without considering strut clearance etc) would require an offset around the +32mm mark because of the extra width. ie to make a 7in +12mm offset wheel fit isnt a case of shaving just 8mm off the hub surface, but 20mm. Hence why the machining work is done before nut inserts are put in.
On the other hand, isnt a +35mm offset 7in rim kind of a standardish front wheel drive rim spec??
