Multiple Failed Clutches

I’ve had two clutches fail within about a 30-40,000 mile period. I’m wondering if something could be wrong with my clutch fork or the transmission input shaft… or anything else!

I no longer put a lot of miles on the car. 1991 Integra, stock transmission. I had an ACT stage 2 pressure plate with a sprung 6-puck, about a third of the fingers on the pressure plate bent downward after only putting a few thousand miles on the clutch.
I then replaced that clutch kit with a stage 1 Exedey clutch kit. This clutch has lasted around 30,000 miles, give or take. Around 5,000 miles ago the clutch cable broke. I replaced it. Now this clutch failed. The basket on the clutch disc cracked and broke in multiple places around the outer edges. There is still plenty of friction material on the disc. At first glance the pressure plate appeared OK, but upon a closer look I noticed the fingers were grooved where the throw out bearing rides. The fingers were grooved much deeper about 180 degrees around (the opposite side).
The throw out bearing was replaced with each clutch kit.

Does anyone have any insight to what might be going on? The clutch fork feels rather stiff to move (with trans removed). Could there be a problem with the fork? Could the clutch disc be getting stuck on the input shaft splines?

Thanks in advance for any advice or theories!

My first thought would be to check the flywheel, get it resurfaced or replaced. Was that done the first time you replaced the clutch?

Update:
After disassembly, I found the basket on the clutch disc had cracked/broken in multiple places. The input shaft on the transmission has a lot of play in it and caused the clutch to fail.
I’m going to disassemble the transmission, replace the input shaft bearing and inspect and replace anything else it may need.
