The wheels are Wolfrace, known as Slot Mags. Usually seen fully polished on hot rod/street machine type cars and Often seen on 70's fords.
I have 5x 6" wide ones, these were originally 4x120 and have been re drilled to 4x100 between the original stud holes - These are the ones on my car plus that spare one that I chucked a scrap 165 on to see what it looked like. I also have a pair of 7" wide in 4x4", and the pair of 8" that were originally 4x108, which I've drilled to 4x100 (see further back in my blog). I bought the pairs because they turned up at the right price. I had hoped that the 8"s were a high enough ofset to fit a bit better on the rear, while waiting for the 7's to crop up.
Unfortunately all the wheels are made with the same back space, so each increase in width pushes them an inch further out.
If only I had a another pair of 7's, There wouldn't be any problem, 165/55s with a nice subtle stretch all round. Lovely.
