Brake pad grease carbonization with track use

gpa7pk

Tracked the Z for four runs and had to "retire" after the clutch failed. The clutch failure could have been prevented if I had followed the forums advice and used RBF. But that is not the reason for this post. Upon removing the Carbotech brake pads all the pads, shims and anti-squeal had the brake pad grease completely carbonized. This occurred between the pad and shim and between the shim and the anti-squeal. Is this normal or did I use the wrong Nissan recommended high temp molly grease? Is there a preferred product?
On the four corners of each pad that ride on the caliper I used very high temp copper anti-sieze with no apparent issue, This is not recommened for the pad, shim and anti-squeal.

Another question is if pad grease should be used between the anit-squeal plate and the caliper pistons.

Carbonized pads and shims are VERY hard to clean......

After thought: Should the shim and anti-squeal be used on the track at all?
