There was no lip on the discs at all? The rears had a nice lip when i changed them.Jeepers you really did knock 7 bells out of those disks.
The new anchors look great behind your alloys, top job
How tight were the tolerances to get the disk lined up with the caliper? Were both sides pretty similar?
On the inner face of the old disk, it doesn't look like the pad was sweeping to the edge of the disk.
Were the old disks lipped or scored?
If the fluid was in a similar condition to your disk's, then new fluid will have given a decent improvement to the bite.
