That car is on RCE yellows with a drop of only 20-22mm (.80 inch approximately). Look at the angle of the axle during cornering and large bumps. Now think of what the angle would be with the car lowered 2-3 times that much.
This is a problem on many cars with independent rear suspension that are lowered not just the BRZ/FR-S.

A longer shaft in a lowered car would be a good start. It's tracking at the end of the race and you can see where it pulls itself down under power to cause the indents towards the outer range of that movement.
That wear suggests the car was lowered early on and either heavily tracked or had engine mods?
It's no wonder they are failing when the CV's are being pulled to their limits at an angle.
