Looks like a decent price for a good tool. No affiliation with the seller just thought it might be useful for some of you guys.

says in the add ." will not fit Porsche Wheel pattern ".

Easy fix to make it it Porsche. Cut the bolt holes open on the outer side of the plate. I have cut open a couple of them. You can get fancy and weld on some 1/4 metal to the outer edge over the bolt holes if you want to but It does not seem to be needed.
