Can you explain why hub centric wheel spacers need to be fastened to the hub or wheel? (Not being critical, just trying to understand how best to achieve this in practice with a 10mm spacer). Given they are held tight between the hub and the wheel by the wheel bolts they can't rotate or move laterally unless there is catastrophic failure of the bolts or the wheel. So what is desired to be achieved by fastening them, and therefore, what is the recommended technique? Thanks.

Tap a thread into the brake disc and drill a matching countersunk hole into the spacer. Screw together, job done. Hope that helps. |

So a single screw is sufficient?

So a single screw is sufficient? Per wheel spacer, yes. |

Can i add to this question ?.....
I didnt want a wheel adapter but from what I have read if i want to use a wheel rim with same pcd as hub (120.65) but 84mm (3.3in) CB I need a adapter
to fit the hub of 70.66mm (2.78in) holden HQ to Chev Rim even though the wheel nuts center the wheel ? is this correct
Also would this adapter need to be screwed on like above ? can it be made from Alloy ?
Cheers

Cheers Hi, sorry I need to break this down to get my head around it. You want to use a spacer and have a hub with 120.65 PCD with 70.66mm centrebore and a wheel rim with 120.65 PCD with 84mm centrebore? If this is correct, then... A spacer must be spigoted to support the weight of the vehicle (instead of the wheel studs supporting the weight) A spacer can easily be made with a 70.66mm female spigot against the hub and an 84mm male spigot to slip into the wheel Yes, a spacer will need to be screwed to the hub Yes, they can be made from alloy, but must be from a suitable type of alloy like 6061 - T6 An adaptor may use tapered seat wheel nuts to centre the adaptor to the hub and centre the wheel to the adaptor Or if you are using a style of wheelnut that does not have a taper, then the adaptor must be spigoted. No, an adaptor does not need to be screwed to the hub Yes, they can be made from alloy, but must be from a suitable type of alloy like 6061 - T6 As a side note, if you are going to make your own spacer/adaptor, then talk about this with your certifier prior to doing so, as there are requirements about who can make spacers and adaptors. You can download a copy of the CCM from here for free - www.lvvta.org.nz/shop/chapter-12-wheels-and-tyres/ The requirements for spacers and adaptors begin on page 20. Cheers Chris |

Yes, these can be used to centre a wheel, presuming you are not needing the spacer/adaptor any more? |
