Doesn't the car wobble or shimmy at higher speeds, not during braking?

Take off the rotor and check the runout off the axle flange.  Warped rotors can be deceiving.

I thought I did that already? (first two photos) Also, I should point out that I did also measure around the outside of the flange and it showed ~0.015 of run out; just in case you were speaking to that.

I wasn't logged in so the photo's were not in your post. I see now. Forget my reply.

Could it have anything to do with the rear disc conversion?

Sure it has vibrations, but what car with this much rubber doesn't pick up NVH as compared to stock?

There is was/a notable squeak as the rotor walked the caliper assy in the caliper bracket, it goes away under light braking.

As for the conversion being the culprit - unlikely. As the other side is perfectly fine; unless of course you are suggesting I damaged something in the process - likely. ;)

Nah - just wondering if it changed the geometry enough to allow something to bend/warp driving it the way you go.

Have you jumped any hybrids lately? Dukes Of Hazzard style?

Mine's as smooth as glass at 118.

I'll say this for the car and vibrations... I couldn't feel a damn thing wrong at WOT in 3rd last night. The car was hauling ass in the cool Fall air.

Only the outer face needs to be true and could be machined?

Not a chance in Hell.
Thanks for the detailed explanation

and welcome back Ed!

 
Eeyeah,my bad.
You can't bend an axle that much and not impart serious stresses to it.
On a regular passenger car,you might be able to straighten it and get it to last,but in the performance envelope Mike's using it in,I wouldn't chance it.
Remember that the axle bearing race is going to be tweaked too,so machining the face true isn't going to help that.

FYI. Bear can't supply a stock replacement 28 spline axle.
