I am trying to justify to my techs why the rotors were riveted to the rear axles and front hubs instead of slip fit. My guess is ease of assembly on the line. Any guesses?

Re: 65-82 Why were the rotors riveted to the axles
They were very aware of the run out problems. I think that the last machine process was done with the assemblies assembled as a unit in order to make sure they were runnout free. -
Re: 65-82 Why were the rotors riveted to the axles
Ken you do not have to have the rotors riveted if you are only driving the car from the trailor to the show/judging field. The spindle and hubs were trued as an assembly and the assembly rivetted to maintain the trueness to be installed in 65-82 Corvettes. For safety reasons I would not have a 65/82 driven on highways and interstates that does not have the rear spindles and discs riveted like the factory did it. Just contact Bairs and ask them why they offer the service of rivetting and truing these assemblys. It is a safety issue. Mismatched assemblys can have enough runout that you will lose all hydralic braking function on the rear wheels. Runout will pump air into the rear calipers. Not a good experience when driving down the interstate and having to come to an emergency stop for the pile up ahead.Comment

Thanks guys for the response, that is exactly what I suspected.

Given that the majority of 65-82 Corvettes
have had at least one rotor replaced in the field and that probably only a handful have bothered with the re-riveting operation, I'm curious that you state there's a 'safety' issue.
It's well known that a replacement rotor can potentially exhibit lateral runout on the friction surfaces which leads to air pumping as you state, but this is due to lack of final machining, not lack of riveting.
The wheel lugnuts offer more than adequate clamping force.Comment
