How long were the bolts? Standard is 28mm, so +15mm for spacing, you should have bolts around 43mm, 45mm will be fine.

It can be easily seen when installing if the bolts were too long, other than that, check for anything obvious, it can only be related to wheel play/touching or bolts as theyre the only things you modified, Jack wheel up, see if it spins free and straight, any play, then check bolt size.

well at least that rules the fault being from those then i can say no you won't be able to use your original bolts not with the spacers anyway  :laugh: 45mm tbh is fine as they pass thru the threads of the hub by 2mm and iirc theres at least 5-8mm before the bolt would bottom out on anything

it is strange but could point to your bolts as its not unknown i should know when i did my fronts i required 41mm bolts so ordered 43mm as nearest size got them delivered and tbh assumed they were correct  :laugh: erm epic fail fitted the alloy back on and wound a bolt in and wtf it bottomed out measured the bolt thread and it was 50mm  :angry: :angry:

found out what the probblem was, wasnt bolts grinding, the screw that holds the disc in place had snapped and made the wheel have play so everytime it moved round it was knocking. anyone had this problem using spacers as both sides had snapped?

the screw should have nothing to do with it mate, the wheel bolts will hold the disc in place...

Got 15mm spacers on the rear of mine with no problems
