My car is primarily a track car running a 4Piston K24 NA engine making around 280whp and 200wtq.
The issue that I've been having for a while now is when on track, and when things seemingly get hot, the clutch pedal doesn't come back up off the floor during gear shifts. And I'd have to use my foot to bring the pedal back up.
I would clutch in to grab a gear, and it would be hard to move the gear lever into a gear as if the clutch wasn't fully disengaging.
When I first encountered this problem last year, thinking it was air getting into the hydraulic system. I replaced the clutch master cylinder, slave cylinder with new OEM units, and stainless braided clutch line and I still am encountering the problem despite replacing all external clutch parts with new components.
Have bled the clutch slave countless of times with various brake fluids (Castrol SRF, Endless RF650, Brembo 64T)
I'm running the Verus clutch fork with Kpower steel flywheel and Exedy stage 1 clutch.
Strangely enough, this problem only occurs when things get hot on track with repeated redline shifts, and the car shifts fine on the street after everything has cooled off.
Also any tips on how to drop the transmission with the engine still in place? Seems harder to do with a K-swapped car than the stock FA20 setup. My next move is dropping the transmission to inspect all the clutch components.

Overfill the clutch fluid reservoir. Fill to the absolute max you can The pickup at the back is going dry under braking, and you are sucking in air on the downshifts. I had this problem on my FRS race car when I still had the FA20. I spent six months chasing my tail to figure out what was happening.
