    Bolt size to install 18z to B7

    Guest-only advertisement. Register or Log In now!
    Hi there. Does anybody know the bolt size that I need to install the 6 pot calipers into the B7 S4 knuckle?

    I know that the top part needs to be 16mm and the treaded part is 14mm of width.

    But does anyone know the length and the type of thread?

    I placed an order with JHM but they donít seem to have them in stock.

    measure the thickness of the boss on the calipers & the boss on the hub (knuckle).

    you can get these to measure with:
