Clutch pedal too soft/no feel? Remove the helper spring!

I find the response "mushy", especially from a stop, but I don't find the clutch engagement all that unusual. Engages near the top of the throw, friction feel is not great, but overall very linear. I've driven performance manual cars for years (two Z06's, a GTS Viper and a FFR Cobra), so I think I have a decent grasp on proper feel and operation.
I'll add in my 2˘ worth too . I do agree on the throttle response - the immediate off idle seems a bit lagged. That can probably be fixed via programming. I recall on the motorcycle's powercommander programming, more programming granularity was available at smaller throttle openings than larger (2, 5, 10, 20, 40, 60, 80, 100% throttle positions). Not sure what uprev allows, but likely similar. Something else to keep in mind, it is a fine balance too. If the throttle is too responsive, slow speed driveability will be negatively affected.

I think the bigger issue at play is the small friction window in this clutch design. Great for the track, but really keeps one aware during street driving. Other performance cars i've driven such as the wrx sti had a larger friction zone window. While this can be remedied with a different clutch or the RJM pedal, after 18 months, i've more or less gotten used to it. To get smooth shifts, more focus is required while driving, so less attention is spent on distractions

In fact, the small friction window may be perfectly fine for the 370z, nissan chose to duplicate the drive line for the G with no significant changes, which is not a sports car by any measure. So we're both stuck dealing with the same issues. They did omit the SRM from the G version.
