The pedal has a assist spring which eases pressure with foot on floor, This is aggravated even more by #1 and #2
If you replace #1 and #2 with a ZSpeed clutch/flywheel package this all goes away 
A lot of people blame this on the "Rev Hang" but in reality it really has nothing to due with how the stock clutch drives and also is not because of the heavy flywheel (this is ECM controlled) Old cars used to have "dashpots" on the carb which would slowly bring down the throttle.
The rev hang actually allows quicker shifts to the next gear as the RPMs are matched better. |
Hey Joe, I actually ended up just purchasing a stage 2 quiet clutch and aluminum flywheel from you after asking you for some suggestions. It feels way better so far and I can actually feel the clutch engagement with the CMAK. Once the break in period is over I'll see how the faster shifting is but so far just normal driving it shifts ten times smoother. Starting from a stop has also been greatly improved. All in all I love it and the trans rattle is in my opinion way better than stock, at lower RPMS there is some but at idle with the quiet clutch I can't even hear it where with stock it sounded like someone was making a nuts and bolts smoothie. I will definitely be sending all my buddies your way.
