Clutch Fix #2 - Oh what a feeling :)
OK..... This is part 2 for our clutch mods.
Give me some feeling in that thang!!!!
Firstly....
USE EXTREME CAUTION!!!!!
- Follow the instructions, but undertake this mod at your own risk.
We are dealing with a spring that is loaded & under pressure!!!
Secondly.....
This mod will not be for everyone because it does increase pedal effort slightly.
So if you do a lot of stop & go..... meh
That said, the pedal effort does not increase too much, maybe 5%
AND, it's not hard to try & then revert back.
-------------------------------
With the Nissan clutch design, there are two springs in the system.
The spring(s) of the pressure plate, which are what actually make the clutch work by holding the friction material against the flywheel.
AND
A second booster spring at the clutch pedal.
This mod is dealing with the spring that is immediately beside your clutch pedal,
and has no effect on the pressure plate spring(s) or the function of the clutch.
The two sets of springs act in the exact opposite direction to each other.
So, with pedal at the top, the booster spring is compressed and loaded.
What this does, is make it a little easier to push the pedal.
Also, it acts as a buffer to make the full pedal travel effort more linear.
The side effect to this is;
It masks the feeling of the pressure plate at the pedal.
It's this booster spring that makes our clutch so dead when it comes to feel.
When I first tried this mod, it really felt weird.
I was ready to put the booster right back & go no further with it.
But after a test drive it was;
WOW.... holy schit, I can actually FEEL the pressure plate.!!!!
I have driven it for a week now & there is no way in hell I'm ever putting it back
I came through a set of twisties this morning that require a rapid high speed to lower speed transition.
H&T down from 5th to 4th to 3rd was like magic
Lurching at a stop light is a thing of the past,
running up through the gears is smoooooth.
The pics pretty much tell you what you need.
Basically;
- hold the pedal down to the floor to un-load the spring (Tie the pedal down)
- remove the spring clip
- remove the bottom pin
- take note the order of assembly, so that you can put it back.
- after testing, (if you like it) remove the top pin to completely remove the booster spring assembly
Again CAUTION!!! with the spring under load.

Any G37 guys try this yet? The 07+ G35 sedan guys have been having pretty good results.
I guess this is actually clutch fix #3 if you say bump stop is #1 and adjusting the threaded rod is #2. I didnt have good results with adjusting the threaded rod, so I am looking forward to this one.

Have had mine out for about 1,000 miles now, I LOVE it, would never go back,,,
It does require more effort to push the clutch, but it is so much easier to drive smooth. You do have to give it a chance, as it feels weird at first.

this mod is sweet, i just did it. took less than 10 minutes to do
-push in the pedal all the way
-2 small flatheads to take off the locking clip
-push out pin
--> at this point the big spring, little spring, and peice fell down onto my floor mat lol
so i was like screw it, i just put the bottom part without those 3 peices, pushed the pin back in, and locked it.
-test drive.
--> the pedal is a little softer for the first few mm's, so i assume it wouldn't be good to rest your foot on it.
-you can actually feel the vibrations a little from the clutch, it's awesome..
-and the engagement and transitions of each gear are butter smooth now.
i'm leavin it just like this, its much better.

I did it too. I had the rod mod up to now and that wasn't enough. Slightly better but it was still the hardest car I ever had to drive smooth.
I did the spring mod this morning. It took a few seconds to pop it out and then drove it for 35 minutes in mostly stop and go traffic.
It feels exactly like my 06 maxima which was a much easier car to drive smooth. It is a bit stiffer but I think that's because my leg went soft trying to learn the stock clutch setup.
The only question I have now in my mind is who the heck drives these cars at the factory and signs off on that ridiculous clutch setup as being satisfactory.

I've driven with this mod for about 3,xxx miles, No problems here. Makes driving alot easier for sure, city and aggressive driving. The clutch doesn't spring up fast towards the top of the engagement anymore. You can actually feel where the clutch engages now and ease it into the next gear. Highly recommend this mod.

I drove this for over 800 miles and it feels good. Only have this mod, not #1, not sure if I should do the other as well, as I got used to the clutch engagement. I'm still a little rough on 1-2 shift, but getting better. Only gripe is the top of the clutch is loose for a few millimeters like everyone else mentioned. I wish that could be adjusted somehow

I have done both mods to my clutch and it feels really good to drive now (2XXX miles). A lot easier to get smooth starts and shifts from 1-2. I find it a lot easier to downshift also. I would highly recommend doing both seeing as how easy and inexpensive they both are. If you dont like it, you can always revert back to the stock positions.
It did take a little getting used to, but it was a lot easier than learning to shift the car when I first got it. Shifts can also be accomplished faster I have noticed.

nevermind, got it out...finally. going for a test run right now.
edit: the engagement point felt shorter than before, felt weird as heck after driving it for like 2 years. theres no lag on take off and its much smoother. i like it...if you have a 6mt, you should try it out.
