What age and mileage is your car? I'm very surprised your not getting any clutch issues on stage 2+, I have found mine on stage 2 has big clutch slip problems. It may be worth upgrading it anyway as this may fail safe it for future, just a thought.
On a side note I've heard the southbend clutch has a pedal feel near enough to standard, Sachs has a heavier pedal feel but I'm going for that option.
