That's just interior trim I assume, and not things like the spare tire, back seats/seatbelts etc. which were already removed?

I pulled a fair chunk of weight out of my vehicle with things like the rear wiper + motor, all of the lines going to the rear window washer + motor, antenna wires and rooftop antenna, etc., though I'm sure I've added it back and then some with sound dampening.

That’s just the dashboard and console so far. All seats are present, as is the spare and jack. I haven’t yet put together another method of getting down the road after a puncture

I wonder if the lug pattern is the same for Honda and GM? I recently swapped the spare in my wife's Fit for an extra Insight spare I had in the basement, which was an easy 10lb savings. If you can find one in a junkyard it could be worthwhile, as they're fully alloy and featherweight.

It’s 4x100 bolt pattern with I think a 67.1mm hub. An Insight spare might indeed work and cut some weight. I plan to daily it with a spare and jack unless I come up with a better and lighter solution, and remove the back seats and spare for events, given that it takes ~5min

If it's still in the car, the Insight jack is also made out of some exotic material.

The center bore is 56.1mm for my Honda. I think it's 57.1 for the Saturn. Might still fit? If not it probably wouldn't be too hard to remove 1mm of material.

So I need to find someone parting a G1 Insight? Or perhaps would it be better to find a single 14x5 alloy wheel snd put like a 155/50 tire on it?

So I’ve worked more on the weight loss. I took a long hard look at how many people travel with me in the car and proceeded to remove the front passenger seat and it’s seat belt. I also have managed to chip most of the asphalt based sound deadening off the floor and ripped out the headliner, dome light, third brake light and the upper pillar covers. Also cut some useless metal off the package tray behind the rear seats. Current weight is 2620lb with a quarter tank of fuel. That’s an honest 50lb under the original weight, which doesn’t sound like much, but...

I have the redline front clip and side skirts which were heavier than the sedan counterparts (that hood was a lot heavier and it’s lifted with gas struts instead of held up with a prop rod)

I added bigger front sway bar and a rear sway bar

I still have the pizza pans on my wheels, as well as the wheel skirts, rear spoiler, and rear lip

I’m still 120lb over my goal of 2500lb or less but I’ve come a long way and you can really feel it in how the car drives; on cool evenings it really moves out for what it is!

I may have missed it but what are you running for a battery?

Currently Iím running a stock group 75 flooded lead acid battery. I could swap to a group U1 lead acid battery to shed around 30lb (itís still just big enough to start the car) but I havenít done it for no other reason than my current battery works. What I really want is a 4S1P pack of Headway 40152S cells mounted under my dash. That would save even more than the group U1 battery and I would save a few feet of cable too. Problem is that I daily the car even in winter and we all know how LiFePO4 handles cold

I used an LiFePO4 pack for two winters, starting my car. It isn't ideal, but the pack did survive a couple of -20F mornings where it still cranked things fine. My recommendation would be to pair it with some moderately sized capacitors.

I now run the lithium pack during the warmer 7-8 months of the year. I just swapped my winter SLA for the lithium pack last night, in fact.
