everything is said.
without reworking the rear arches, maximum is 7,5" ET35.. and sometimes depending on the make of tyre, you have to pull a little bit on the arches.
I had the case when I fitted the V8 wheels on my 200, with Bridgestone RE720 tyres (205/60/15).
A friend of mine has also put the V8 wheels, but for him it was ok, the tyres were in the same size, but not from Bridgestone
you could find some 200 20V front wings here :
