Thank you lord! I still have problems from 1st to 2nd, i thought it was just me getting used to a MT again.

It sounds just like my 06 G35 I used to have. It wasn't the power of the car because i've driven cars with less power and torque and also cars with more power and torque but it was just a tricky clutch to get used to.

IDZRVIT 06-16-2012 11:50 PM

I didn't read all 11 pages but I will say this. From my experience, my two Z's, '09 coupe and current '10 roadster, shift easier than my previously owned '96 Ford Aspire and current 2011 Honda Civic coupe. There is nothing wrong with the gearbox in a Z other than the annoying clunk.

Jsolo 06-17-2012 12:27 AM

Before getting my G, I test drove all 3 (370z, g37 coupe and sedan). I honestly can't say any of these three shift differently from one another. In stock form, all have vague clutch feel with narrow friction zone. The weaker clutch spring does help alot. However, if you got $$$, there is a fully adjustable replacement clutch pedal assembly available. IIRC something like $200 or $250 for the kit.

More info available here *RJM Performance.com - Home

For me, the weaker spring is a fine fix. I'm used to driving cars with heavy clutch pedals that have high uptake and small friction zones (my late 90's camaro was very similar).

Ive only owned my z for a month and I do notice the z's clutch tends to feel just on and off. Ive driven other cars and IMO its probably the most challenging (but not difficult) cars to drive.

I messed around with shifting the car when I frist got it to get used to the clutch. Ive noticed that when you engage the clutch slower and release normally it tends to be smoother between shifts for 1st and 2nd. Thats what work for me, i dont know about everyone else.

stalled once so far, but it was because I was trying to feel for the sweet spot in the clutch haha/:driving:

AlphaSnacks 06-19-2012 12:14 AM

^^^Yeah, slamming the clutch down too fast in 1st and even slower speeds in 2nd, makes this awful noise of the clutch and flywheel disengaging.

Face 06-19-2012 12:49 AM

There's a parking garage I exit often that is on a slope and terminates into traffic so the transmission is under stress as you slowly spiral up the slope and then you're forced to abruptly engage the clutch and brake to avoid a collision and then you're greeted with that "clackity clackity clack" sound.

I hate it.

shika805 06-19-2012 01:03 AM

^weird i've notice that to with my car?!? I dont know what the hell that is!

wow the small things that annoy us about our z's haha

JohnsZ 06-19-2012 10:56 AM

I've had my 370Z for just about a week now and have gotten the shifting down to a science especially going from 1st to 2nd. Very simply...make sure your RPM's are between 3K and 3.5K. Smooth as silk :)

Z34Driver 06-19-2012 11:05 AM

I did not / have not found this car difficult to drive, just different. I got right out of a 2000 Honda Civic Ex MT (Since 2001), into the Z (2012) and drove off the lot with no problem (no stalls). The Z has basically 3x the HP, which is one of the main reasons it feels different for me :tup:

This could have something to do with the method used when I was taught how to drive a manual transmission, and my dad never letting me forget that when girls are riding in the car, they don't want to feel you shifting gears...He parked in the middle of a hill in my neighborhood, told me when I could get up the hill, I could drive a manual trans, this was in a '98 4-Cylinder Ford Ranger...He's not a redneck haha.

if you stall this car, you definitely suck at driving MT's... lol

Persnickety
 
I find that the combination of a hydraulic clutch, overly helpful helper spring, meager low end torque, a very short clutch engagement and a choppy 'digital' throttle make for a very difficult-to-drive-smooth car.

I'm surprised there's not more bitching on here about the hydraulic clutch. I've never driven one I like better than a cabled version. They just seem to remove all the feel. Not to mention the 'bounce' that hydraulic circuit can introduce. It's like a resonance wave in the hydraulic fluid - get the release wrong and it can induce crazy clutch chatter. I've never experienced clutch chatter on a healthy cabled clutch but find it to be pervasive on hydraulic clutches.

That being said almost all those issues become moot when driven aggressively. When I'm really getting on it I don't even for one second think about anything but how kick *** this car is - which is, of course, why I bought it!

Well, considering that there are now at LEAST 11 pages of posts on this topic, it is clear something is not as good as one might expect in a modern sports car. While I had adapted to the clutch quirks in this car, I am not one to settle for what the factory provided if I don't like it. So, I investigated and made some changes and am 100% happier. My investigation revealed 2 flaws:

1. (as others also have noted) the engagement point is too high off the floor, causing one to have to modulate at the engagement point with one's knee up in the air. Not optimum. Can it be driven this way? Sure. Would ANY race driver (not that I am) worth his/her salt NOT change it in order to improve overall performance? No.

2. The return spring on the pedal is not a simple affair. It is a linkage to a spring unit which is oriented 90 degrees away from what you might expect (for space considerations, I'm sure). The relationship between pedal motion and spring compression is not linear. It is a sinusoidal relationship. A sine function 'rate of change' (slope of curve; energy needed to move the pedal) passes through zero and 'infinity' (changing from positive to negative at each of these points) as the input (clutch pedal position) changes. This friggin linkage goes through the 'infinity' point in the relationship right about at the engagement point.

If anyone does the adjustment detailed in the other clutch thread, they can experience this first hand. With the clutch push-rod disconnected from the pedal, move the pedal through it's range of motion, starting at the pedal fully 'up' position. Push, resistance, push, resistance, push SNAP the pedal goes to the floor and stays there. You have to pull it back up (with the master cyl push-rod attached, the clutch spring, fed back thru the hydraulics, pushes the pedal back up). Pull, resistance, pull, resistance, pull SNAP the pedal snaps up to the fully 'up' position. The SNAP occurs where? Right at the stock engagement point. Maybe this was on purpose... the pedal 'helping' inexperienced drivers to get their foot off the clutch pedal once the thing is engaged.

The net result is a distinct change in pedal response, right where I least want it. What to do? Well - fortunately- when the push-rod linkage is adjusted, the relationship of pedal-position-to-engagement-point is changed, and the spring snap-over occurs well past the engagement point, as I am taking my foot off the pedal.

As discussed above, a good driver can compensate for a lot of faults in the car (Fernando Alonzo in a 2009-spec Renault F1 car comes to mind as a possible pinnacle of that!), but don't overlook the fact that many faults (such as the clutch action in our 370Z) CAN be fixed.

I agree most with Turbodog.

1st I did the clutch helper spring, didn't feel a perceptable change
2nd I adjusted the pedal engage point, night and day difference

What I still think is still wrong with it...
1) Springs in the clutch plate are too soft giving it a choppy engagement. In my opinion, that's the jerkyness you feel getting off the line sometimes.
2) Pressure plate is too soft. You should be a able to get more snap out of it. Hell, my leg doesn't even get tired in stop and go traffic.
3) I'd like a lighter flywheel too. You shouldn't see a big change in RPM during engagement anyway. It's just there to make getting off the line easier.

I'm not going to take the transmission out to fix this stuff untill it needs to come out for some other reason.

Davey 06-21-2012 12:31 PM

Yeah, the heavy flywheel is not what I'd like to see in a sports car.

I'm OK with harder to drive if there is a reason for it. It's almost like SRM was an excuse to use an even heavier flywheel and have a laggy throttle response. Trying to heel-and-toe the Z without SRM is pretty frustrating.

Is it just me, or is the pedal position awkward for heel-toe as well?

Been a while since I tried since I got frustrated with its unwillingness to rev, but I want to say they're too far apart and the brake is too high to have it work unless you're on the brakes REALLY hard.

I dont have any issue at all? Pedals are in great position for me. Its very easy car to drive on the street and heal toe is quite easy. However I grew up heal toeing old Porsches so my perspective may be warped. I have to admit though Im cheating on my feet and having an affair with SRM.

I tend to fat foot it more often than not... the gas pedal is definitely set back further from the brake pedal than any car I can remember driving more than once. Even when you're braking incredibly hard with the brake pedal mashed in, the pedal is still pretty far back. My knee ends up hitting steering wheel and/or column without some serious shift of my a$$ in the seat

First time trying to manually heel-and-toe will frustrate the hell out of you because it did for me...lol. I kept practicing until my foot became natural and my foot just does it automatically now. So it seems hard because of the pedal position is straight up, long, and you have to hit it up there to do it smoothly, but as everybody says, practice makes it perfect. However, mine is still not perfect though, but getting there almost!

Z34Driver 06-22-2012 09:44 AM

While I didn't stall driving it off the lot, I do remember a few things that were strange about the clutch pedal / pedal orientation after first purchasing the car. Every time I would shift, I would accidentally still have my foot on the gas slightly when engaging the clutch. This would cause the engine to rev, like I was trying to blip the throttle to downshift, except this would happen when I was shifting up. Thinking about it now, this probably does have much to do with the orientation of the pedals / and strange clutch release point.

I've never owned a car worthy of the track, at least to me, so I've never really driven in a "Race" environment. So I guess for me, I just adjusted to the car and really haven't had any issues with driving it since the adjustment. I'm sure my size 14's don't hurt though, when it comes to reaching the awkwardly distanced brake, and gas pedals at the same time.

RC24 06-22-2012 11:02 PM

So after owning my Z for 5 days now, the clutch pedal has been the one thing that has been bugging the hell out of me. After searching the internet for the past couple days, I've found some information on how to adjust the engagement point, but nothing that made me feel confident in doing it. I saw B&W_Evader's post from a couple days ago that he had adjusted the engagement point, so I sent him a PM. His response is super simple, and doesn't need any pictures to figure it out.

B&W_Evader:
"Stick your nose under the dash and draw your attention up the pedal linkage. You will see a bar that goes into the floorboard. This is the bar that goes to the clutch master cylinder. You will see a clevis connecting it to the pedal and a lock nut that keeps the rod from turning. I just loosened the nut and screwed the rod in the whole way. You may not need to go that far but I had only about a turn of adjustment. I used a needle nose pliers on the nurled portion of the rod to turn it in. The posts I read said you need to watch that you don't take any of the switch positions out of place but I didn't have to do anything on mine."

In addition to the needle nose pliers, you will need a 12mm open ended wrench to loosen the jam nut.

Once I got under there and figured out how to work in the tight space, the mod took all of 3 minutes. From when I went out to the garage to when I was starting the engine to test drive it took about 5.

Huge difference, and now the clutch feels more "normal" to me (based off of the last 11 cars I've owned with manual transmissions) I took it around the block and didn't have any grinding issues or anything weird like that.

Just hoping this post will help some of you who are searching as to how to do this mod and haven't had any luck.

ALTN8NRG 06-26-2012 10:02 AM

As far as stalling it: It's the exhaust restriction. I stalled mine a couple of times with the factory exhaust. After putting on Fast Intentions exhaust I didn't have issues with stalling it in first. The manual Z is work. Sometimes you have to drive it like you don't give a D#$% to make it move. Just do it.

Read this whole thread and already got you bookmarked LMBmikeZ when I need the spring. Got a 2013 on order and will see how it feels first.

But, got a couple questions, can you lower the clutch pick point and use the new spring as well? Or would doing just one work fine? What have you guys done out there?

LMBmikeZ 06-26-2012 10:31 PM

The spring is the best bet because that will control the feel and how much back pressure there will be against your foot! The adjustments as outlined by B&W invader can still be done when the clutch spring is switched to get the desired location and set point of a depressed clutch.
