New Z1 Clutch failing at 2k miles...?

Spaghetti999

Installed new JWT HD CSC, OEM CMC, and Z1 Clutch & Flywheel Kit (Standard full face/z1 performance midweight, RBF 600 clutch fluid

6 weeks later, 2.5k miles later I am starting to feel vibrations in my clutch pedal when shifting between gears. One week after vibrations first noticed, at above 4k-5k rpm shifts (spirited highway driving), my car gets stuck in a gear and I can't get out to up/downshift...Takes a few tries, then once out of gear it refuses to go into gear without a few tries again. Pedal suddenly becomes floppy, basically loses some firmness/pressure for a few seconds similar to feeling when CSC gave out (just not as severe).

3 seperate issues
1. vibrations in clutch pedal
2. engagement issues (can't get out of gear/in gear under spirit drive)
3. Pedal will lose firmness immediately after engagement issues occur

This wasnt a problem when spirited driving for the past 1,500 miles after clutch break in. Why suddenly now? Loose bolts?
