Holy thread resurrection, Batman! I started this thread with a question about 10 months ago. My original question was intended to be where I could buy Alfa-specific spacers. Because they were going on my race car, I wanted to make sure they were hub-centric and specifically for a 4x108 pattern. That way they don't get out of position when you are constantly taking wheels on and off. While the Pep Boys variety are inexpensive, I try to just use them on my street cars. I ended up buying some 1/2" spacers from Jack Beck rather than having them made locally.
