Update:
After not driving my NSX for a month, I decided I might as well do something with it while it sits in my garage for the winter to keep myself occupied. I'm going to attempt to shed more "free" weight off the car this week.
Tomorrow I'm planning to remove the sound insulation behind the seats. I'm also contemplating an idea in regards to the carpets.
Last year I removed my carpets entirely and tried it out for like a week. I liked the weight savings but I didn't like the somewhat exposed look of the floor. Additonally when the carpet is not installed the wire harnesses are all out in the open exposing them to potential damage. Today I came up with an idea that might look very OEM but reduce weight at the same time. I'm thinking of sacraficing my carpets and cutting the base off but leaving the area that covers the wires on the perimeter of the floor. I would then either paint the remaining section of the floor black or use the floor mats to cover the bare floor. It should look very OEM but still remove a good amount of weight. If I remember correctly each carpet in it's entirety is 7lbs each but I could be wrong. Considering my carpets have like 2 or 3 cigarrette burn marks in different areas it not like I'm ruining a perfect set either. Here is a picture comparision showing you what I mean.

What do you guys think bad or good idea?
I think I'm also going to remove the fan in the engine compartment and also remove the center speaker since I'm currently not even using it. Hopefully I can get a total of like 30-40 lbs out of the car with all of this.
If my estimations are correct that should put me under 2900lbs with a full tank. My car weighed at 2860lbs with half a tank of gas last year, when they did my corner balancing after I installed the KW V3s. Since then I've installed my my comptech headers and exhaust which I believe I saved about 10-15lbs with that.
Another idea that I haven't really seen people do is remove the intake manifold covers off the motor. From my understanding these magnesium covers don't really do anything except display the Honda plate on the engine.... If this thing weights a substancial amount I'm removing it.
Additionally today I ordered the NSX-R chassis reinforcement bars and the downforce scoop. I'll probably install those next week when they arrive.
I'll keep the updates rolling in as things keep progressing this winter.
