I knew there were 2 types and I have learned on here that 20mm is the optimum size to fill the arches. I just wasn't completely sure if the PCD was correct. Although, I hope these are the bolt straight on efforts - can't be arsed tapping! If you scan down the page, even though auction has finished you can still see them sungod.
Thanks 3FIDDYZ! Gotta love a bargain. Do you think they are the straight bolt on efforts?
