Bad Clutch Disc?

[Allboost429]

I purchased a act 2600 clutch package with a 4 puck unsprung disc (solid hub) I also have a Fidanza aluminum flywheel. The problem is i had about 7000 miles on it and on my way home from work. I went to get off at my exit when i pushed the clutch in to down shift it started grinding really bad. The cluth would not engage after i got stopped. When i dropped the transmission and pulled the clutch disc out the inside of the clutch was totally smooth. All of the splines were gone. but the shaft was not damaged at all?? What would make a clutch disc go bad so fast? The clutch was never dropped during those 7000 miles!

Wow that sucks. Did you have the flywheel steped for the clutch, also what type of TOB did you use?

yes the flywheel was steped for the clutch. It has 20 psi but a 4 puck would hold 20psi easy
