SRT8CUDA Build

When I was installing the brake rotors, I found a lot of runout on the rotors (~0.030" on one and about 0.015" on the other)
After eliminating the rotors, I found that the axle face was not true!!
Another call to Bill Reilly, who contacted Moser and I got an immediate callback from Foz at Moser.
He said they try to maintain the face runout to 0.008" but will allow up to 0.020" total. I said that that would result in a max runout of 0.040" on a 12" rotor, but he thought that would not be a problem!!
After he explained how they were machined, I went back to my machinist and we measured 0.018" and 0.011" runout.
Normal tolerances on todays vehicles are typically <0.002" max runout on a rear disk rotor.
Had my machinist press out the bolts, set up the axles in a lathe and remacine the face. We easily achieved <0.001" runout.
We can't figure out how the runout could be so great. Modern machine shops should easily be able to get this face <0.001" runout. maybe the flange is distorted when Moser presses in the bolts?????

Mumble, mumble, mumble!!!
