I'm just wondering what swamp did in his case with the RACs, if he switched them out or if the light marking on the inner barrel eventually went away. I've got to make a decision here shortly.
Have you tried PMing him? I think you are right, one data does not a trend make. The bolts will eventually "clearance" themselves by gouging out the aluminum on the wheel so I don't think it's a good idea to just let it "go away". It could weaken the wheel barrel and create a perfect failure point.
