Yes they are GermanLook wheels, that is what most GL's used originally I believe before the newer style wheels came out in 17 & 18 inch sizes.
I like them alot, especially polished they look great!
As far as fitment, 6's in the front should be no problem at all, niether should 7's in the rear.
Go look at Porsche Killer in the Feature article section on the main page.....
