[Fot] Rotor runout

[Scott Janzen]

Swap rotors to the other side and find out if runout is the same. I gave up on turning rotors - too many runout issues and new ones for the gt6 are $25-30. Not much different from having them turned, though it seems like a waste.

My pads were pulsing pretty bad at the last race so I had the rotors turned at a shop I trust. 

Upon reinstall today I found that I had 0.010" of runout on the passenger side rotor. I repacked the bearings and I use the spacer kit which was setup with about 0.0005" of play. I was curious so I measured the runout on the uncle jack hub wheel flange and was surprised to find 0.003" of runout in the hub. 

On the driver's side, rotor was 0.003 and hub wheel flange was 0.0005". 

Did my shop just do a horrible job turning the one rotor?  What kind of runout is spec for the uncle jack hubs?  Is it possible that a wheel bearing race has gone wonky on the passenger side hub to cause the whole hub assemble to have the runout?
