Is there a problem with rolling the under side of the arch up? I did that for my 16x9s on my Mk2. There was no cutting just a bit of bending the lip under the arch back using a baseball bat and a heat gun. Took me about 2 hours to do both...But that included pulling and reinstalling the G60 Flares. I can't tell from the picture if you can do that but it seems to be possible (mine had a 10mm lip that could be bent up flush with teh under side of the fender)
