1990 Z32 TT.

 

So I was stripping the interior of my boot lid to refurb the rubber seals etc, and noticed this block attached to the bootlid.

 

I thought maybe it was part of the mechanism for the (removed) rear windscreen wiper, but there are no connections. It's just a metal block connected by rubber to the brackets that bolt it to the bootlid via the holes to the left and right of the block in the picture (2x10mm bolts).

 

Just wondering if anyone knows what its purpose is? Weight distribution? Bolt on block to replace a windscreen wiper mechanism?

 

Cheers

 

 

Its a counter weight, i got rid of mine years ago :thumbup1: serves no purpose other than supposedly give some even weight distribution between front and rear of the car

Ayye good good! Cheers

When the car was new and the gas struts were new, and there was no water was in the original spoiler the metal block weight was so calculated to give the tailgate enough counter weight so that a small assist to raise it was required without it shooting up too rapidly.

 

Over time however the gas struts get tired and the original spoiler takes on water both of which upsets the calculation making the tailgate heavy to lift up, taking the weight out will assist to a degree, but in general changing the spoiler will cure a heavy tailgate.

 

Jfef

I never knew that!!

Haha is there anything about these cars you don't know Jeff? :P

 

Good to get it cleared up, cheers.

 

Bit of weight reduction eh

He isn't sure how to fit a Flux Capacitor and go back to 26th October 1985 at 9am.......... Not yet anyway..... lol

 

But give him time..... :whistling:

I thought it might be vibration in panels lots of cars have blocks like that underneath.

A bit of it was rubber and could move, if it was just for weight would they have not just used solid metal...

Like these things

 

Z1 sell some very strong gas struts, i just pull the lever and up it pops and i still have the weight :smartass:.

My old purple zeds struts were fairly new feeling as even with the extra weight when I opened the boot it felt like it took off most of the time.

Yours are pretty strong..... You'd probably be able to flip your car back onto its wheels if you ever ended up on your roof :lol:

Appreciate this thread is a year old, but only Terry got it partially correct.

 

It is certainly not a counterweight as it would serve very little purpose at that. What it actually is is an anti-vibration device fitted to reduce 'flutter' on the tailgate created by resonance at certain speeds. I wouldn't remove it personally, the weight is insignificant and hardly worth ditching.

Getting very technical here Si and had to look up this high speed flutter and came up with this :detective: Hope the rear wing of the Z does not vibrate to much lol

Yeah, well fortunately I don't think if a Z32 boot flutters, it will break apart! :lol:

yeah that weight is long gone m8 but better late than never eh. If the Z makes it out of my driveway one day I'll find out

Don't worry about it cozza, it will be fine without it

Every little helps...

Weight a minute...

You have to ask yourself the question that if the function of this weight was simply a static counter balance why did

Nissan go to the trouble and cost of suspending the weight on elasticated rubber supports?

It's actually correct Jeff.

Exactly. It's self explanatory once you look at it (I hadn't previously), it's also diagonally placed for that reason to help with resonance in wider angle.

 

I'll happily get it confirmed from the horse's mouth with Toshio San at ZCon in a few weeks. It was brought up a number of times before.

We believe you mate :yes: There is just so much we don't know about the z32 and learn new things all the time. I wonder it there are any other cars with this fitted.
