Bolt size to install 18z to B7

[joaobatta]

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 don’t seem to have them in stock.

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

or you can grab a set from us:) https://www.ebay.co.uk/itm/292674772668 , because you will need the sleeves also, from 14 to 16mm
