So do you think the ball be paired with the throwout then? I see you're saying 'buy both' but fuck that's a lot of work to R&I the transmission for science.
Agreed!For my Baja, I matched the pivot ball to the 06+ WRX fork. Full 06+ WRX clutch kit on an N/a trans, ground down the ribs like you mentioned. I never tried a wrx clutch fork with an N/A pressure plate, disc or flywheel though.
Sorry that my info isn't too pertinent.
For anyone else reading, if you have the 92-05 WRX style trans, you can use a 6mt clutch kit with that, takes a little grinding inside the bellhousing near the starter. Advantage is oem feeling clutch that holds more power (compared to stock ej205 clutch).
