my G and dd both have better clutch feel and throttle response so it made driving my Z feel kinda odd the first few miles until i got re-familiar with the Z's characteristics ever weekend.

so i swapped out the clutch spring which made a 50% improvement, and the latter 50% just got a sprintbooster to rid the latency. car feels as good as my G35C which is very good. my G never had a latency issue.. throttle input was instantaneous, clutch feels more like the old traditional clutch.

about the csc.... i think if you're easy on the clutch pedal input you're going to be fine. same issue on the G35/350Z.... mine is fine. 10yrs original owner.
some folks just ram the clutch pedal like no tomorrow and that's too much instant pressure on the little cylinder.
