When I did exhuast on my 2004 roadster we found a weight in the front left corner under the black engine protector flap. I took it off with an impact and it really doesn't change the way the car drives at all. So if you want to shave 15-20 lbs knock yourself out... your welcome!

 

I discovered this weight last year when I had my TT kit installed. At that time there was some discussion on this forum about why it was there. The general consensus was that it was to balance the car better since the roadster has the motor to operate the top. My installer said that the FMIC for the TT would make up for any weight loss by removing the plate.

 

I've heard everything from counterbalance to noise reduction... I don't think anyone really knows why it's there. Some safety/design weenie put it there, nice thing is with one bolt you can take it off.

 

You are correct...there is another one of those weights in the back passenger side in the trunk under all the carpet etc.

I heard there was another someplace else...

 

If its only 15lbs I would keep it in. The weight reduction wouldnt be that noticeable and you have to think that Nissan put it in there for a reason (like balancing). Nissan tends to cut costs every chance they get so they wouldn't have designed and installed this weight without a reason.

 

There's a reason why these pivot, and are at opposing corners of the car.

 

everybit counts. 20 here 10 here 15 there.. soon 100 off. thats like having passenger but still maintain same weight as if you didnt have one

 

I will leave mine in. I am sure that Nissan did not put it there just for ****s and giggles

 

we nick named it "The ********"

It kinda sways around...

its some kind of dampner... There is a specific name for it...

 

haha Jason. is that ? mark for your next car? LOL

 

Is this only on the roadster?

 

yes. I am buying the car today...

no more Z in a couple more hours...

 

These weight are put in other brands roadsters/ convertibles as well, deleting the roof will result in dramatic structure chance of the body strength.
Partly solved by reinforcement structures as X-brace and door latches.
To change the vibration frequency by putting counter weights is a easy way to stop vibrations before it building up and become so strong that they will affect eachother what mayaffect loss in handling, or cracking of the floorpan.
Remember the bridge that collapsed because of the vibration frequency amplified ?
Note that car manufacturers never will put extra parts (cost) in their cars if it is not necessary.

 

That's the flux capicitor, it specifically says in your owners manual not to remove it.

 

The roadster has 2 under braces that the coupe doesnt have...

 

just wondering, what car are you buying Jason?

 

We had one fall out on our mechanic as we took the wheel well out, it was loose and fell out..

 

I am no longer a Z owner...

I am now the proud owner of a 1996 240SX...

Im working on a post about it...

 

Was it for ease of modding?

 

No, but I also have access to many many 350Z's (stock) to try new mods on

Its mainly a $ reason... Payments were cut down to about a thrid of what I was paying before...

For those who dont know, I got my Z before I started working at performance and was upside down over 10K...

I made over $25,000 in payments to my Z in just over a year and a half, and still had a $24,000 buy out before I could get the 240...

If I would have kept the Z, it would have costed me well over $50K... I decided to cut my losses, save up some money for a while, and then heavily mod the 240...

Then eventually get a 4.0 Frontier and tow it...

I will miss my Z very very very much... I loved that car... (except after I put it back to stock, its hard for me to drive a Z without the tilton in it...)
