Could you label the parts in that picture? I'm not quite sure what to do still...

I still have a little bit of play in the clutch after installing a new spring (the play doesn't bother me so much as the noise it makes... as heard in this video another member posted: Clutch - YouTube)

I'm surprised more people haven't commented on your fix. Has anyone else done it?

^^With any clutch, you always want to have a small amount of play. This ensures the clutch is fully engaged when not depressed.

I'm in for a GB also.

This literally changed my 370z life...

Ive been driving manuals for about 10 years.... always been able to jump in any car and go.

I was JERKY AS HELL in this car. Felt like an idiot. Thought something was wrong with the clutch / axles or something...

Removed this, and all is smooth as butter. And its honestly not THAT much stiffer. Just alittle bit more. Feels like a real clutch.

Just did this mod and man, amazing. So much smoother!!!

hmmm.. might have to give this a try
anyone have an extra spring laying around?

airikrankin · 04-23-2012, 08:25 AM

interested as well, i also almost stalled it while pulling out of the dealership, thought it might have just been because its new, 1k later still sucks in for a group buy?!

was reading on the G37 forums that there could be some damage associated with this mod.
DIY Clutch Fix #2 - Oh what a feeling

Something about a similar mod being done to corvettes and the play at the top of the clutch petal messing up their master cylinder. One guy there said it may have contributed to his clutch going bad in his g37. Any thoughts guys?

haven't heard of anybody to have issues. there is a way to remove the play at the top though by adjusting the pedal.

I haven't read of the Z/G design having this port, but for added peace of mind, most of us are replacing the spring with a weaker one rather than eliminating it altogether. This takes care of the small amount of play at the top when pedal at the top of the stroke.

I'm not too fond on having a clutch with no play at all. You should always have some play to ensure clutch gets fully engaged.

So i just did this mod... Is it me or is the difference really minute in terms of feedback on your foot. I feel like the pressure to push it in is the same.

The only thing i noticed to this mod is that the clutch is now predictable. You know when it is engaging so it helps with the 1-2 shifting. Also i feel like the clutch sits closer to the firewall now.

Jsolo · 05-01-2012, 11:47 AM

I thought there was a rather pronounced difference - both with no spring and with the weaker spring (as compared to stock), in both the down stroke and up stroke. You have less assist pushing down now, and no buffer on the upstroke.

In general, the whole point is to better feel the engagement when you're lifting on the pedal. Unless you made other changes, the pedal extremes should remain the same (how far to the floor it goes and how high it comes up).

Thats wierd... unless my foot is so damn heavy that i can't tell lol

But for reals in terms of the pressure being pushed back at my foot, i feel its the same as stock.

I wish our clutch felt like the STI's clutch. That one gives you one hella of a feedback and is stiff. feels really good.

Jsolo · 05-01-2012, 01:19 PM

^^You think so? I test drove a '11 or '12 sti and thought the clutch was rather light. Not as light as in the z/g in stock config, but much lighter than what I was used to. It did have good feedback, and a lengthy friction zone.

Seems the big trend in feel is what you're used to. If you have an opportunity, test drive a 4th gen camaro (93-02) or camaro/ss, or better yet, a 70's muscle car
