Post #4
I took the wheels off for some measurements tonight and I was a little surprised with what I found, the 330mm bells aren't significantly thicker if thicker at all than the normal disks so I ruled them out as causing the problem.
I'm using the proper OZ spacer kit which is a 26mm spacer and 50mm bolts. I roughly measured the brake disk at around 7mm and the wheel at about 1cm thick. After the spacer that only leaves around 8mm to screw into the hub.
From a quick google it seems the minimum thread engagement needed for M12x1.25 bolts is 9 turns which would be 11.25mm in the hub, I'm only getting about 6-7 turns.
After 6 turns in the hub the bolt will still wobble, after 9 turns it is rock solid.
In my (uneducated
) opinion it seems the OZ spacer and bolt kit isn't fit for purpose, and I'm fairly sure it's the cause of the clonking noise I've been getting recently which goes away after loosening and re-tightening the wheel bolts.
I'll be finding different fixings asap.
