Group Buy - Clutch Pedal Assist Spring for 6MT
5/21/2024 Update
In stock - usually ships within 1-2 days of payment.
------------------------
As most of you are aware, the 6mt clutch pedal has very vague feel due to an over compensating clutch helper/assist spring. Some have removed it completely, but in doing so, there is no spring force to bring the pedal all the way up.
Got my 2012 6mt just a few days ago and same issue. Pulled the spring and it feels a whole lot better. However, I'm not entirely comfortable leaving it without the spring, especially on a brand new car. So after much research, I found a thread over at the 370Z forums where a member sourced a precision spring, and to cut costs did a group buy.
Here's the thread (21 pages long) - Clutch pedal too soft/no feel? Remove the helper spring!
One of the thread posters had his OE spring measured at 334 lbs/in. The replacement spring is spec'd at 52 lbs/in, or about 15% of the OE. Enough to bring the pedal back up without interfering with clutch feel.
Spring specifications:
OD: 1.100"
ID: 0.860"
Free Length: 2.500"
Spring Rate: 52 lbs/in
Wire Diameter: 0.120"
Fits all G37 6MT's -- all years, all body styles

Here's some comparison pics I took before installing. New spring is ~1/16" taller

Installation instructions
**Not responsible for any injury or damage sustained to self or vehicle in the installation and use of this product **
Tools needed
* Safety Glasses
* some means of lighting up the area under the dash - I use a 12V heavy duty portable lantern
* Needle nose pliers - need a medium size tip to grab the C clip
* small flat blade screw driver
* a mat of some sort to sit on next to the car
Here's what the whole assembly looks like in the car (weaker spring already installed)
A close up of what needs to be removed
Using the small screw driver, rotate the C clip so that it's oriented as in the pic - opening towards the front of the car. Using the needle nose pliers, grab at the center of the clip (circled in red above) and pull straight out. DO NOT REMOVE the top clip/pin, it's not necessary for this mod and is difficult to reinstall.
At this point, the assembly is under load and the pin will not come out.
You will need to depress and hold the pedal to the floor in order to unload the spring and be able to slide the pin to the left, out of the clevis. You don't need to remove the pin entirely from the assembly, it just needs to clear the bracket. A helper may be useful. I usually depress (and hold) the pedal with the left hand, while working the pin out with the right.
Once the pin is cleared of the bracket, pull back out on the entire spring(s)/clevis assembly to remove, replace with weaker main spring and reassemble. The small top spring and hat gets reused.
The pedal will have to be held to the floor in order to get the clevis to engage the bracket. It's a bit tricky, but take your time getting everything aligned. Some might find it easier to get the clevis on the bracket first, then slide the pin in. I usually have the pin partially started in the clevis before reinstalling/aligning. Sliding the pin in after the fact is actually more difficult because there's limited room to get the pin in (from the left).
The important thing to remember is that the pedal HAS to be to the floor to unload the spring before any pins are removed. It's under significant tension and can fly out causing injury/bodily harm if removed forcefully with the pedal not fully depressed. This only applies to the pin, not the C clip.
After the pin has been pushed all the way through, you can release the pedal. Reinstall the C clip by holding it in the middle with the pliers and push straight onto the clip. If the pliers are not perpendicular to the middle of the clip, it will be difficult to apply force without the clip rotating.
The entire procedure shouldn't take more than 5 minutes to do. It will take much longer to read and under stand these instructions than to actually do this.
In stock - usually ships within 1-2 days of payment.

First post updated with all payment received so far. For you early subscribers, please submit payment as i'm definitely placing the order tomorrow.
Also, if we go over 10, that's fine too. I'll order extras anyways since I really didn't expect the response to be so quick. Last group buy I did took over 3 weeks to submit the first batch (an HID headlight kit for the motorcycle).
I'm out until evening tonight, so you won't see any updates until then. Thanks again!
