1.063" front discard thickness
1.0236" rear discard thickness.
I dont believe those are the correct parts for the V3.
Front rotors, GM PN: 84271643, Rock Auto is 1771247
, does not list discard thickness. Probably due to the 2-piece? Not sure.
Rear rotors, GM PN: 23369743, Rock Auto PN 1771214
, discard thickness is listed as 0.2834646 or 7.2mm.
I also recently replaced my rear rotors at 30k cause they were worn, I didnt measure them. I checked them for any markings that show the discard measurements and didnt find any markings of any sort.
