A solution for this can be to replace the spring for a much softer one. Then you will retain the additional support without the unwanted assistance of the stock spring. Someone on the G37 forum suggested the softer spring to take care of the little slack at the top, but I assume it'll work for this as well.

yeah that would in theory take care of both problems, now to find a spring

there is a few "clutch fixes" on the other forums, this one seems to be the simplest/ least involved.

I am a bit surprised because some of you feel the clutch pedal too soft... From my point of view, the clutch pedal is pretty strong, even if the feeling is strange (bouncy...). Of course I still have the spring installed, but I wanted to know what is the normal feeling of the clutch pedal. Mine is not soft at all.

the clutch on these cars is the lightest clutch pedal I have ever felt in any car. you don't feel the pressure plate at all with the spring installed.

the local hardware store/big hardware store sells tons of different kinds of springs!

Drive a Volkswagen or Audi ... there is no feel in them in comparison ...

I did it. Definite improvement.

The slack is still there, but decreased. I am going to look into getting something in the springs place just to add support. If that doesn't work out, I will just reinstall the assembly (rather not though).

I'm actually looking for a weaker spring, I'll update the thread if I find something suitable.

Can you remove the spring and then reinstall the assembly and pins? I'd guess that would give lateral stability to the pedal without the resistance of the spring.

Is anybody available in the bay area (cupertino or San jose West) with a manual transmission 370Z so I can evaluate my clutch feeling ?

I tried looking at a diagram in the FSM briefly, but it doesn't look like it would do much. The problem is that it's not the pin assembly by itself that gives the pedal it's stability, but rather the heavy spring forcing itself upwards against the pedal. Even by repacing the spring with a softer one than OEM you could theoretically keep some of the stability, but it still wouldn't be close to the OEM specs. Realistically speaking, it's up to those who choose to do this mod whether the percieved benefits outweigh the potential long term issues.

I'm in East Bay but I frequently go down to the South Bay areas. If you want, we can meet up sometime or set up a small meet this weekend.

you can't just remove the springs and re-install the assembly unfortunately, honestly this isn't that much of an issue from what I can see, the pedal has little side to side movement. G guys have been running with this removed for years and not reporting any problems.

I'm just looking into replacing the spring for longevity if its a simple case of finding a proper spring. If I don't find one im certainly not going to re-install the old one.
