Did the clutch helper spring swap.
I was skeptical at first, but hey... I'll try any $10 mod just for chits and giggles.
My impression? Do it!
This simple mod reduces the amount of force pushing the clutch pedal up from the floor which makes it much easier for me to operate and engage the clutch smoothly between shifts and especially when searching for the the friction point for perfect launches.
I can only guess that Nissan must have thought that the extra stiff spring they put on the clutch would make the car feel more sporty. For me, it just made the car a little more tricky to drive.
