I used a baseball bat to seat to hold clutch down. My pin wouldn't slide right either though, I had to hold it with a locking wrench and wiggle/pull out.

I think enough people have given this a thumbs up but what's one more. After picking up a Z a couple days ago, introduction on the forum and further details forthcoming, I thought at first the clutch was just stiff and the car was just new to me so was just rusty and I'd get used to it. Well after 12+hrs of continuos driving it still felt numb and the engagement point mysterious. I thought I had lost my mojo despite driving a stick off and on for the last 18yrs. Decided to look it up and found this thread. Immediately removed the spring (was super easy) and went for a drive.

Night and day difference. The feel is there now. Easing on the throttle is much easier and predictable. Incline starts are also very much improved.

Considering ease of mod to measuable benefit, I'm not sure it gets better than this.

Thanks everyone. Looking forward to being part of the community here. Seems like a great group and theres not much that hasn't been covered.

hmmmmm might try this, when I first heard about it there was about 2 guinea pigs but now theres lots lol.

Where do we get the softer replacement spring some folks are using?

I bought one for my 2011 Z but never installed it. My 2014 doesn't need it. I'd sell mine, PM me if interested and can't find it elsewhere.

It's a Century Spring P/N 72577

I did this mod years ago on my '09. Got my '14 and was like WTF, this is crap, had to do it again. Great great mod that actually gives you tangible results.

I got mine from JSolo. He has a thread on the G37 forums with buying info. Just PM for details if he hasn't found you first.

Great seller, fast shipping and worthwhile replacement. Very happy with mine. Feel more comfortable having something in there vs leaving it out.

I do recommend swapping vs full uninstall then reinstall. I had a period of time I had it fully off but it would have been much easier to just swap with the new. Then again, I wouldn't have known how bad I wanted to replace the stock one until I felt the diff of not having a helper.

Just saves pulling the top pin which is a pain to get in and out without the risk of dropping it behind the plastic paneling while also holding the clutch in. :)

Stuck, removed the c clip, but can't get the pin out. Tried pushing down on the clutch and removing the pin, but it came out half way and can't seem to get it out. Any help?

If you got it part way out, can you get some vice grips on there and leverage it out the rest of the way?

Is there one or two c clips? And I've tried that, seems so stuck!

Sorry for the revival.

Just did this and the clutch feels like a normal clutch finally! Just for peace of mind, its fine if no assembly is in place correct? I dont have a replacement spring so im just riding with nothing there instead. I know someone said earlier that it shouldnt affect anything but im wondering if anyone located any problems (over time)? just want to be sure im not hurting anything:driving:

Not sure if this was mentioned or not but I thought I'd add something.

After removing the helper spring and re-installing all of the other OEM components (another small spring and what appears to be it's housing) the clutch felt MUCH better. That being said, I would occasionally feel a "pop" when fully compressing the clutch and letting off (in every gear). This "pop" would end a little bit into my "sweet spot" making it hard to smoothly get the car rolling. After getting back under the seat... I realized that the smaller spring was getting stuck to the housing and popping out. This is a result of no tension on the smaller spring due to the lack of the OEM spring.

I removed the smaller spring and housing... VIOLA. The clutch is pretty much perfect. I don't think I'll be purchasing an aftermarket spring!

TL;DR = Remove everything you see below!

I was getting the same "pop" and wondered if I could remove that part. Glad to hear that you can :tup:

I never messed with it and got the RJM clutch pedal assembly instead. If the spring replacement/removal doesn't satisfy you, I highly recommend the RJM pedal :driving:

Funny, I just got to driving the car again from winter storage. I kept saying, "what the hell is wrong with this clutch?" especially in 1st gear. Its been 5 years now and I still feel like a newb in 1st with this car. I am going to give this at try right away.

So what is the consensus, just remove both springs vs. buying a different spring?

Yup Exactly. Do you guys know where to buy this spring?

I may go with the rjm pedal. I've had the other spring for a while and after a while you don't notice a difference anymore and it's still jerky

Step 1: remove springs
Step 2: don't buy new springs
Step 3: take wife/gf to dinner with the savings
Step 3: buy self beer

I would like of like one as well just to compare between no spring and the new spring. Let me know if you find someone selling and I will do the same...

Also, you can buy online but its a minimum of $40 plus shipping, which is why I assume people were group buying...

Found this as well...

INFINITI G37 G37S G35 NISSAN 370Z 370 Z 6MT CLUTCH PEDAL ASSIST RETURN SPRING | eBay

I just bought it. I will report back when I get it and install it.

Alright, so I took the stock spring out but then a small spring came out too?
Do I need to put the small spring back? If yes then where does it go?
Everything came out kinda quick that I didn't have time to see how the small spring was setup.

I put everything together withouth the 2 springs. Took a 10 mile ride and everything works.

Please advise. Thank you
See image below (warning it will probably be a big image don't know how to make it smaller)

Its perfectly fine sans both springs

This feels sooooooo much better than with the spring. WOW! I don't really know why Nissan puts this crappy spring in there. This is how a clutch should feel for sure! I already order the new weaker spring and will arrive on Tuesday.

Really! Why the hell did Nissan design it that way? So dumb!

Looking at the mechanic of these springs. It would probably be a bit harder to press down and stronger on the return. Is that how it feel after the springs removal?

To be honest with you, it feels "softer" both ways and it does not assist on the return as much as with the spring.

The new weaker spring is being delivered to me today. I will report back in a couple of days.

Installed the "softer" spring. Feels much better over stock. Great feel! Feels like a normal clutch now. Hopefully they (Nissan) learns about this and apply it to the next Z.

I took off the spring all together to see how it felt. Im not getting that "wow" factor like a lot of people on here are. I still feel like that pedal is stiff with no feel. I guess its slightly better but not as much as I had hoped for. 1st gear on this car is still frustrating to me. ive been driving manual since 16 yrs old and this is the only car I have ever driven where I get nervous if on a hill stopped, and worried ill stall, buck the car, or get it into gear at a higher RPM than desired.

Oh well...

:iagree:

I haven't owned any cars that are automatic (only rental cars when I do work trips) and 1st and 2nd gear in this car is a bitch.

Glad its not just me lol:rofl2:

is this spring mod the same as doing the RJM clutch pedal?

no

I think the real issue with the clutch is that it engages high without any modulation. It is hard to slip the clutch for a smooth engagement like other cars.

If you analyze the mechanics of that spring, the oem one actually make it lighter both way because the spring compresses when you release the pedal and decompresses when press down. So if you remove or change to a lighter spring, all it does is make it harder both ways. It does nothing to resolve the issue of engage point and lack of modulation.

However, I am sure that we can master it by paying more attention to where the engagement point is and release the clutch accordingly. I found shifting at 2500 rpm from 1st to 2nd generates less jerkiness.

Just purchased the replacement spring from eBay, thanks for the help finding the spring guys!

I'm going to be doing this mod tonight. I did it on my Mustang a few years ago and I know it's pretty straight forward.

Before I do, I have a couple quick questions.
1. Is there any downside to this? Yes I know, I'm sure someone asked and answered but I randomly looked through 4-5 pages of the 37 and didn't see anything with certainty.
2. Are people generally doing the removal or putting the softer spring in. I only did the removal on my last car.

TIA

I tried the softer spring for a few weeks, didn't feel like it made a big enough difference in feel. Ended up deleting the spring and the entire spring carrier assembly from the pedal. I also adjusted the little threaded clevis where it attaches to the clutch pedal. Much better than the factory setup IMO, although I do plan to get an RJM pedal eventually, this is good enough for now.

I removed it completely. :hello:

I removed it but didn't like the free end-play without any spring, so I found a much softer one to put back in.

Fair enough. It doesn’t bother me.
