Do you guys know where I can find a listing of all sizes/offsets/bolt patterns a certian wheel was made in? I am doing some research on some Kosei K1 Racing wheels. I need to see if they ever came in a certian bolt pattern and size. I have been searching on google and not much is coming up. Also I have called Tire Rack and they do not have a listing of all of the sizes. They can only see the sizes that they carry. Any help is appreciated.
