Now, with that said, Z transmissions have super soft syncros and baulk ring clips that tend to break and fall down into the bottom of the case. This is what actually causes the grinding issues experienced in most older/abused transmissions. It has nothing to do with the strength of the gears.

Yes and No.
Torque, Grip & Shock is what breaks the drive-line. I've seen plenty of Z32 / R33 gearboxes give on drift cars with 400+ tq that have decent grip. i can honestly say 99% of Z32 guys make 600hp with 500+tw and never see a track event. All they do is rolling burnouts on summer tires racing other cars on the street. nothing that comes close to the abuse of a real race / abusive situation. Drag racing is abusive but not as bad as drifting. Launch control hits the driveline once, drifting hits the driveline multiple times per run. so it's comparing apples to oranges.
