DIY: Weight reduction/Fix hatch not opening issue

Remove the weights from both cars and spent 60 cents buying 16 washers (4 for each car) for spring helpers. Sorted..

Thanks again for this DIY fix/mod! I was very hesitant to take the panel off myself because of the clips, especially those white ones! Was going to bring it to stealership to get it looked at, but I just went ahead and did it; and I'm glad I did!

Since this post I've had to add 4 more coins on each side. I cant add anymore else it the rubber doesn't close/fit.

Problem has been back

I have read about the useless weight in the rear trunk lid. I was bored and thought I would have a go at releasing some weight on the Z! To my surprise the weight was not part of my factory install. I guess I am happy. I wanted the satisfaction to remove it myself though...

Hmmm, I wonder if my '16 Nismo has it? Too lazy to find out but I have no issues with my hatch so I guess I will leave it. I'll bet the weight was left out of all redesigned Nismo's ('15 and up). Maybe someone with an earlier Nismo will chime in.

My understanding is that the weight was added to keep the hatch from buffeting and vibrating at high speeds. I spoke to a friend of mine that works at Nissan R&D.

I've never heard any buffeting coming from the hatch since removing it.

Removed today the weight from MY2013 Nismo

This helped, and it now pops up if I press the button once!

I tried this (weight reduction and 2 nickels each side) and it worked for a while but now it won't fully open. Does anyone know where to get spring replacement that's either bigger or stronger than stock?

Just pulled out this weight out of my Sep 2009 370z.
The hatch seems to close exactly the same as before, whereas when opening it, sometimes it pops fully open (one handed opening), sometimes I need to help it up. Anyway, I'm happy to have removed it.

I've got these springs. Very high quality and the hatch opens everytime
