Hi what Porsche wheels are you looking for?
I'm changing the look of my buggy and I'm taking the Porsche turbo twists off, they are Mille miglia copy's bought from machine7
The beauty is they we're spec'd to fit on a beetle so they are all 7" but the front are 55mm off set and the rears are 23mm, I've not had a beetle so I can't be sure but they are supposed to fit under the arches using Porsche pattern discs on the front and Porsche pattern drums on the rear, I had 944 discs on the rear and it pushes the wheels out by 25mm per side.
Now I was going to wait till the after Christmas when people may have more spare cash before selling them but might as well offer them now.
They have very good tyres, in fact the rears are new, the fronts are 205/45/17 falkens and have about 700 easy miles on them, the rears are 215/45/17 toyo proxes (tr1's I think) and as said they are new, I used theses toyos on my focus and loved them, way better than the yokohamas (even at 130mph
3 are perfect and 1 has some slight kerbing I was going to put them up for £350 which is about what the tyres cost, if your interested let me know,
