This is my experience also. 20k is all it took to burn up my OEM clutch. I installed CF clutch and it worked great till yesterday when I fell into a couple v notches and gave her more than she could give. Driving home I had to force it into 1st but once rolling could engage 2, 3, 4 with a little extra effort30k miles on mine. I have two different CF clutches in it. This was after OEM would burn after minimal input, for example backing up a driveway.
My shifter engagement stinks. It will hang in gears or not engage. I'll have to rock it back to a different gear to get the gear I want to engage. Strangely, the bottom of the H (2, 4, 6) seem fine, but gets hung up in 1 and 3. If I jog into 2 or 4 it then goes smoothly into 1 and 3.
Either way, a PITA.
I'm over 40 and have been driving manuals since my first car...
