So my Wilwoods are ~30 years old and the rotors are grooved and glazed over.
They are the track only lightweight models.
It's ~3/8" thick, .375" IIRC.

How much is safe to clean up or is it a throw away part??
They are not even listed under rotors??
They have similar, but not the same.

We were going to take a touch off each side just to break the glaze, not fully remove the grooves??
These are the second set of pads on original rotors.

What I have done is chock the rotor up true in my lathe, take my 4 1/2 grinder, and as the lathe is spinning (500-750 rpm) I break the glaze. I use a rubber pad with a 60 grit disc. I would not try and remove material, just get yourself enough of a crosshatch pattern to brake the glaze. I have done this to my 4 caliper rear set up after about the first 3 summers of abuse and it worked well. No issues or vibrations coming down from 162.

The main reason we wanted to do this is to learn.
We now have access to a lathe and have been learning little projects, mostly doing trans stuff.

Mine are as old as yours. I had a machinist in my area clean mine up on a blanchard years ago. I thought I talked to Wilwood and they told me that was how they should be machined. I think there is a minimum thickness spec on them too......

I haven't called them yet, but I didn't see anything mentioned??
I'm sure there are specs for that, like I said, we just want to try it.
These are the rears, much safer to learn on these than screwing up the fronts that do most of the work.

Again, we just want to try the lathe on something different.
I am not sending them off, if we can't practice on them, I'm not doing it.
