Exedy triple problem need insite
Friends clutch started screaming. So we pulled trans to inspect and change tob. Then i found this. The center hub and rounded out disc were brand new and only have roughly 2k break in miles since it was a new motor. Lmk what you think so i can fix it.

wow! I would definitely contact exedy if thats truly after 2k miles. I have around 10k miles on my Exedy triple and havnt seen any evidence of this. I am going to be pulling my trans for a built rebuild this winter. Crossing my fingers that I dont find anything like this!
What the heck happened?! That looks like some pretty serious damage. If that truly is after just 2K easy driving, count me out on the Exedy triple. I don't particularly care for the thought of pulling my transmission out every oil change to change faulty clutch discs.
It looks like that torn up disc has some extra abrasion on the outer edge of the mating surface. Was the release/throw out bearing opening the clutch sufficiently? Were gear changes difficult?

The car it was from.was driving and shifting perfectly normal. Till it started screaching and no wanting to go in gear when pressing the clutch. Happened out of the blue. No heat spotting on the floaters or anything. No real sign of clutch drag. Contacted exedy for him just waiting on a reply.
Known issue for street driven evos. our cars are the only ones with this problem. Either the clutch gets chewed up, or its the synchros. They have a new model that is almost out that should fix this problem. This isn't something I've thought of myself, that was directly from Evan at Exedy. I went through two center hubs (new style) and two sets of discs and floaters until I decided to ditch it.
Theres multiple threads with this same problem on here if you want to read up on it a bit.

That sounds an awful lot like the release/throw out bearing, or slave cylinder had failed, causing an incomplete release of all the clutch discs. That can explain the visible abrasion on the front disc in your pic. Do the Exedy triples need too much release pressure to open, causing premature failure of the release components? Just taking a half-educated guess.
I didn't know this was a problem with these clutches. I'm currently running one, so I hope it stays together. I bought it thinking it would last a LONG time (since I don't really drive the car hard).
this problem is not about power. its about removing balance shafts. bad with 2.0 engine. and absolutely horrible with 100mm crank. the harmonic vibrations are killing the clutch during normal driving. clutches need spring centers to absorb these vibrations. without springs the splines are under great strain. its like an impact hammer effect. this is the result.

Whoa. That does make some sense. But do other multi-plate clutches without springs experience the same failures? And if crankshaft oscillations are killing the splines, that seems like something that would be addressed by now, seeing as how balance shaft deletes have been going on for a long time now.

balancing engine wont do a thing to reduce harmonics . fluidampr is designed to absorb them so it will help reduce the problem a little. balance shafts are hugely important.. think of the shafts eliminating 60% of the vibration and the harmonic balancer another 20%. 20% goes through drivetrain. even with that every car ever made has a spring center clutch to absorb the energy before it gets to trans and driveline. eliminate the shafts and now you have 80% going through with no spring center clutch to absorb it.
