Is this okay on a wheel in order to fit slim spacer nuts under? Have been relayed information from a friend recently going through cert that this is totally acceptable, and Znoelli offered the service also so it can't be dangerous surely?
It's been done properly and all that, and is only cut down by 3-5mm at absolute max, but just wondering if it could cause any problems going through cert. Again, the certifier I'd probably be using has said that he doesn't mind this at all.
