HOLY CRAP! Thanks for this - just did the same thing (got mine at bed bath & beyond). That **** works! lol.

I just dynamatted my entire hatch. It took 5 hours or so but gave me confidence to rip open my doors too. Go to a dealer and ask the service manager to tell you how to rip open your doors and hatch. They have awesome service manuals that you can look at for about 10 seconds and know basically how to do it without f'ing up your trim. Also there are utube vids how to take apart your doors. They helped me s lot and I did it all without breaking anything.

The Dynamat made my road noise on "very textured" California roads go from unbearable to merely annoying. Im going to do some research on which areas the Dynamat helps most and add sparingly.

If you tap around on your car and find areas that "ping" instead of going "thunk" you can probably Dynamat the critical spots without going overboard on weight.

I carpeted my hatch, and then took a box of 4 sheets and put the stuff up around my shock towers and up in the fenders in all the spots that "ping". It helped a lot. ImageUploadedByTapatalk1346870267.997754.jpg

I'm sure you have already said this somewhere, but how many pounds of mat did you add?

SurfDog · 09-05-2012, 01:40 PM

That shot is about my halfway point. 2/3 of my first box ( I usef two)Once done the thing was blanketed.

If I were to do it again I would tap around my entire cabin and mostly just hit the spots that ping. (to get better results with less weight)

The clutch rattling noise is the dual plated clutch rattling together WHICH IS NORMAL on the 350z and 370z which i have owned/own both.

When you press in the clutch the plates are compressed and then the noise is gone.
Example shut your car off in neutral with the clutch out. Noise will be heard.

Then press the clutch in and shut the car off... NO Noise....

All normal boys its just due to the twin plated clutch.

This has gotten a little off topic, but hopefully nobody minds...

I have a rattle somewhere near where my dash meets my windshield and I can't figure out what it is for the life of me. I thought it was the plastic fittings around the gauge cluster but that doesn't seem to be it. Anybody else have this and figured out what it is? It's driving me insane.

No. I haven't hurd that noise yet... Did anything fall from the dash into the back of the gauge cluster?

I know I was reading someone got a Mini Pen jammed in there and it was doind all sorts of stuff before he got it out.

HKYStormFront · 09-10-2012, 10:14 AM

yup, normal noises. the 2nd gear shifting noise is probably the diff moving a little bit. it's meant to do that (that which does not bend, will break kinda thing). making sure to push the clutch all the way in for that shift may help. also, double check your brake master cylinder and slave cylinder fluid levels, if you are a little low on clutch fluid you may not be getting full pressure on the throw out bearing so the clutch would be slightly more engaged than it should be causing the transmission to "clunk" into gear, tho i would think if that were the problem it would be noticeable on most gears

Hey guys, sorry to revive this thread. I'm a new owner and was searching the forums and came across this thread basically describing what I have.

In neutral, clutch out, idling and I get a whining noise. Clutch in and it's gone. Let it out and it starts up again. Looks to be the input shaft bearing and you guys are saying this is normal? I have 17k miles. Other than the whine, the car shifts fine and no other odd noises.

I'm just curious because I've also read threads on other forums saying that the whine is the first sign of the input shaft bearing failure which can cause harm to the gears and could ultimately ruin the trans. Am I just over-reacting?

forza370z · 03-04-2013, 03:13 PM

Yea it's the throw-out bearing. I think it's normal. Almost every 370z 6MT has this noise and I haven't heard anyone reported any issue related to it. Mine is 09. Had this noise all the time and no problem so far.

HKYStormFront · 03-04-2013, 10:03 PM

yea my truck was the same way, i don't hear it anymore (133k miles) but that's what's got me worried lol

Chuck33079 · 05-31-2013, 10:29 AM

It's the flywheel and clutch rattling.
