I know that most discs are 6 bolt, but what I want to know is the bolt spacing... (for example, a 4 bolt bashring is 104mm, etc) What is the spacing/diameter of the circle that the bolts lie on. Once I know this I can get to work on my next project.... custom discs! :cool:

44 mm - here is one of literally hundreds of different designs I've done. This particular one gets the Galfer patent number enscribed on one leg since it was licensed to be produced in an aluminum version.

Thanks, I needed that... I dont have calipers at home. I'll post a pic of my final design later.
