Ok, So it's a total of $15? i'll send the payment as late as tomorrow ^_^

When I get to my computer I will have to pick one of those up as well.

Payment sent !! ^_^

honestly i got the helper spring, but it still feels much better with the whole spring off.

Took this off today, great little mod! How many of you left the whole piece out all together instead of replacing the spring?

WTB one of the Century springs. Anyone have one left over? PM me.

+1

Check with Jsolo. He might have one or two left.

Sorry guys. I sold the last one few weeks ago. I may do another buy later in spring/summer if there is still demand.

I still have them......

wsup55 & roshdawg you have a pm.

and so do you :tiphat:

Just installed the Century Spring and this is without a doubt, the best thing I have done to the car thus far! The clutch now reminds me a lot of the clutch I had in my 66 327 Corvette and 66 GT-350, with maybe a little less effort. I had NEVER stalled a manual transmission car until I got the Z. Now, I will not stall it again... :driving: :happydance:

The increase in pedal effort is negligible, but the disengagement of the clutch is sooo much easier and smoother now. Good trade off IMO.

On another note, I purchased 4 springs, so I may have 2 (or 3) that I will send to someone who needs one for $15+shipping. Shoot me a PM



[QUOTE=bluenoser;1257678]Ok there's good news and bad news. The Fastenal spring I mentioned earlier doesn't work. The inside diameter of the spring doesn't fit correctly over the assembly. I ordered the day after I measured it and I guess I wasn't paying close enough attention when I placed the order.

The good news is that I found another spring after I realized the error that definitely does work. P/N 72577 at Century Spring is the winner 72577 - COMPRESSION SPRING - Part Characteristics | Century Spring Corp. The spring rate is roughly 20% of the stock spring and it feels very similar to running without the spring installed. The bad news is that you need to order 4 of them to meet their minimum order quantity.

Anyone still have one of these available?

You know, before I go and order 4. If I *DO* order 4, any one interested?

I just removed my helper spring and it feels a million times better. So happy with this!

I removed my helper spring a few mins ago and took it for a test drive and the difference is awesome. I have only had my 370 for a few days and I kept messing up looking like a rookie at manual driving. I would still like to get the Century spring but I dont know if I want to buy four of them yet lol.

I would be interested in a spring if anyone is going for four....

I finally had the new spring installed last week. Effort feels great and natural. It's definitely nice for fast and smooth engagement.

WOW...I finally got around to installing it today and, now, I am giggling like a little girl. The drive feels completely different and EASY! :excited:

I still need one. Who has any left?

Bumping to see if anyone has extras. :ugh2:

Not sure if the 350 has one, i'm guessing not by the feel, but i know the 370 in the UK has this stupid spring as well.

I need one also Im also down for a group buy

I'm in for a group buy of 4 Century springs as well.

same here im down

Ditto

I need one!!!

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?

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 :) - MyG37

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.

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 :rofl2:


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.

^^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 :)
