I recently installed a McLeod RXT twin disc clutch and new McLeod Aluminum Flywheel. Also installed a McLeod Clutch Quadrant and McLeod Firewall Adjuster. The previous setup was stock, and I did not change the stock pivot ball at that time. (Before the install, I had read on SVTP that with a clutch change, some people had shorted the pivot ball, others had lengthened it, some left it alone and it was fine).
I installed all of the above, and no matter what adjustment I made with the firewall adjuster, the clutch pedal was only effective when my knee was in the roof (it engaged/disengaged at a very high point).
As it turned out, the clutch was never totally disengaging. I know this because the engine RPMs were normal, but the car wasn't pulling nearly as hard as it used to.
My problem was that the stock pivot ball was too close to the clutch and the throw out bearing (TOB) was putting too much contact on the clutch fingers to let it totally disengage. This makes sense looking back, because if I had to guess, the new dual clutch assembly as a whole is thicker than the stock one (which puts it closer to the clutch fork and TOB).
My solution was removing the stock pivot ball and installing a McLeod adjustable pivot ball. When I screwed the new pivot ball all the way in to the trans cover (no cutting necessary), it shortened the pivot ball 3/8". (picture attached)
The car now shifts like it used to. I hope this helps somebody out.
