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

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.

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.

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.

After running it for a day, I decided, while it has a more realistic clutch feel, I didn't like the free-play in the pedal. Re-installed for now.

I did this myself and all I can say i love it. Its alot smoother and easier to shift it kinda reminds me of the exedy hyper single i had in another car. The only thing that got me thinking was if there will be any negative side effects. You guys think it will mess something up in the tranny? They put it on for a reason, which I dont know why.

I already read them. The thing is someone came on and said it might cause long term damages. But everyone kinda just went on and still did it. But what if that one person is right.

All I can tell you is that there is very little side to side play with the spring removed. His concern was that it might be possible to put extra stress on the master cylinder because this spring is no longer there. While it's good to be aware of possible issues, no one in the G community has reported any kind of failures related to this mod so at this point its just speculation.

If you are still debating the possible ramifications don't do this mod, the clutch clearly doesn't bother you enough to make it worth it

Why not? I did.

My OEM setup is rock solid and I never had any issue driving, shifting, or bucking. I removed the springs and I can feel the clutch engage better but the slop at the top of the stroke is horrible now. OEM feels better.
