Fitting new disks wiht dial indicator gauge?

[MattSAU2XR8]

Hi Matt,

Hope you don't mind another technical question which may be of interest to other readers also. I've been reading around on the net and come across a few posts that describe checking the axial runout on both hubs and then discs with a dial indicator gauge when fitting new discs, and then trying the disc in different positions to get the least combined runout, if any is present. Theory seems to be that if the combined runout is reduced as close as possible to zero then there is less change of disc thickness variation developing as the rotor wears. Given I can buy a cheap dial indicator gauge for about $45 on ebay this seems like it might almost pay for itself on the first set of rotors fitted. Do you think this is worth considering or are new rotors and hubs so accurate now that there is unlikely to be any benefit.

Thanks for your thoughts,

Matt
