Whenever I feather the clutch to get going in 1st I get a shudder, sometimes violent, presumeably from the rear. The only way to avoid this is to rev up a little first and then release the clutch faster. My RPMs are not dropping below 1k but the shuddering is worse the slower I release the clutch, almost like the clutch is intermittently slipping. I just got my HTG clutch setup installed last week, but I had this problem with the previous OEM clutch. I have also recently started getting the single click from the rear which I assume is the spindle/hub nut TSB, but the shuddering has always been present (at least since I bought the car last year). I did some research and my best guess is that a CV joint is loose? Any opinons?

 

Test if it's the CV joints by getting fully under way (clutch all the way engaged) and then accelerating briskly through the rev range. Try this in first, second and third. If you get the shakes or a vibration, then it's more likely the CVs.
The clicking is likely the axle nut thing.

It may well be possible that you are taking off with too little throttle and the clutch is beginning to grab unevenly and giving you clutch chatter. Hard to say if it's a clutch problem or your driving technique.
This part indicates to me that you are in a "near lug" situation with the engine. This would aggravate, if not be fully responsible for the shuddering you feel. You've done this through 2 clutches, so I'm beginning to think it's not the car.

 

I hope it's not the car. I don't get the shuddering once I release the clutch, only while feathering it. However, I've never had this problem in my Sentra. I probably just need to give it more throttle when I take off. Now that I think about it, this doesn't happen when I'm on the road, only when I pull out from my parallel parking spot. I'm probably just being cautious not to hit the car in front of me and going light on the gas.

 

This is THE biggest flaw in peoples' thinking when they post up questions here.

"My (name your car of choice) never did this."

Did your Sentra have an engine that revved to 9000 rpm?
Did your Sentra have 240 HP out of a 2.0L engine?
Did your Sentra have a clutch the same size and function as that in an S2000?
Was your Sentra RWD?
Did it have a LSD in the rear?
Did your Sentra's clutch operation in the same kind of way?
Was your Sentra's clutch made of the same sort of construction and design?

What "problems" your Sentra never had, has absolutely no bearing on whether or not your S2000 actually has a "problem".

 

The point is that my driving technique may not be the problem. I don't see what the engine, RWD, or LSD have to do with anything. If you're trying to tell me the cars are completely different, I'm well aware of that; but there's only one way to drive a manual transmission and yes, the clutch does operate the same way. Thanks for you're help xviper, I think I've figured it out.

 

Could be the flywheel is warped or some springs in the clutch plate broke. Let us know what it was once youve confirmed/fixed it.

 

I'm sure lots of people are following this thread and not posting. Perhaps you could share?

I would explain why all those things would make a difference, but if you have your mind set, then there's no point.

 

Does this shudder happen when the car is just started being cold?
No?
Because the revs are kept higher by the ECU.
Solution: keep the revs up a bit more when driving away => no shudder

It may be your driving-away-from-a-stop-in-first-gear technique
The engine may act like a normal 2.0 at low revs, you still need some revs te get the torque to get moving smoothly.
RWD may not make a difference, other then you have to spin up the prop shaft, a fairly strong gearbox with lots of gears and a rear diff too, to get moving.
That all takes torque.
If there is only 1 (one) way, then we all have the shudder?
The S2000 clutch was designed to withstand shifts at 9000 rpm and transfer the torque and HP the engine delivers.
Don't you think that clutch is even slightly different then your average clutch?

Anyway..
Be a sport and just try to drive away with a little more throttle, only to see how the car behaves.
You'll be surpriced.

 

Yeah, the shudder happens to me too. I'm 4 months in on the manual driving game, so I didn't want to be a clutch burner. People have told me to make sure not to ruin your clutch since beginners have this problem. When I reverse out of my driveway, I just let the car glide back in reverse, and slowly take my foot on the clutch. I definitely get the shuddering and sometimes hard ones if I lift too much. Just put more gas. It's always worked for me.
