Got it from Ebay. It was a direct swap. The rear one is made from some kind of plastic. So I doubt you can save anything there. Plus most of the weight reduction happened in the back of the car. So I don't wanna do anything there.
There are 2 steel bars that connect rear subframe with the center of the body. They are heavy and flexible. So I replaced them with aluminum rectangular tubes.

And don't forget about engine cover, that's good for another 5lbs, and better cooling. But you will hear that hpfp more. Also, I believe 2018 is the only year that came with aluminum intercooler merge pipe section. That can be replaced with newer plastic one, for another couple of lbs and better efficiency.
As much as I'm nuts about light weight and chassis tuning, these are still first and foremost everyday drivers. I've already cut way too deep into my NVH tolerance scale with the coilovers, I've about reached my limit. For weekend fun at the track/AutoX, yeah, I don't mind ripping out as much as allowed by the rulebook. But everything gets put back in before Monday morning commute.
Those tuned mass dampers on the struts are there for a reason. After I switched to coilovers, I could feel the engine vibration at idle that wasn't there before. Not too obnoxious and not present all the time at idle, but distinctively felt enough for it to be unrelated to the removal of OEM struts. I'm sure the absence of the OEM strut top bearings, with rubber isolators, also played a role. Regardless, the increase in NVH is most definitely there.
That's one area where I'd happily sacrifice an extra pound to quiet that lifter tick / diesel noise from the HPFP. I wonder if wrapping the thing in fiberglass, rubber, or dynamat would muffle it...those things don't run very hot do they?
Looks like the metal bracket above the battery is only there to hold the spare tire up, so if you're removing the spare, you can remove the bracket too.

Our G70 didn't come with a spare tire but did have a different 2-bolt bracket. I had to buy a 3-bolt bracket from a Kia Stinger to mount a spare in it.

It's been a couple years since we did that, but IIRC, it was mostly there to keep the trunk floor package shelf/tray from touching the battery. Don't think either bracket does much to hold the battery down. Maybe as a secondary containment, in case the primary hold down clip came off?
Anyhow, one area for easy weight loss is the exhaust. Those dual mufflers are some 25 lbs each, IIRC. On 4-cyl cars, dual-sided exhaust is just plain stupid. Our G70 6MT came with single-sided sport exhaust that made the same 255HP, so there is absolutely no advantage to having two. It just adds dead weight. That is one area I don't mind doing some custom work to shed some pork. I've already done an axle back for our G70 and it came out pretty good. I just bought a DC Sport 3" front pipe for the 2.0T that I'm going to fit on the 2.5T. It isn't a direct drop-in fit, but pretty darn close. Looks like the only work I need to do to it is to shorten it about 2-3inch. I'd like to insert a resonator inline to tame the planned custom exhaust, so I'd have to cut that pipe anyway.
the difference probably is not that big. But sunroof would add around 40lbs. I know the front seats are 20lbs heavier than gt ones. 19 inch wheels will add another 10-15 lbs vs 18 inch on gt model. Electronic steering column and rear lift gate mechanism gotta be heavier than manual one. Just the stuff that comes to my head. But I wouldn't be surprised if gt2 is ~100lbs heavier than gt.

If anyone can find the torque specs for those 3 bolts for the top T bracket, and the 2 bolts for the bracket at the bottom of the battery that actually holds it down, I'll put a nice star next to your name .
Did you buy it new? Cuz I haven't seen a base gt that didn't come with staggered 19s on it stock. My car is also awd. Only ones I've seen with 18s were the premium and gt-line cars.
