Weight savings ideas for 992?

I believe lightest configuration with PDK is going to be spider wheels (unconfirmed), 4 ways, carbon ceramics, carbon roof, base interior, aerokit

Forgive me for not wanting to scroll through a couple thousand posts in the T thread, but what does a T actually have that makes it more lightweight? My understanding was everything that is lighter about the T is available as an option on at least some other models (LiFePo battery, buckets / rear seat delete, lightweight glass etc). Is that incorrect?
but OP is stuck on PDK so I’d actually recommend a used turbo or turbo s. Heavier, yes, but the power difference will more than make up for it. ( I owned a 991 turbo for a bit and found it super powerful but admittedly boring bc of the pdk. But if you must have PDK, it’s brilliant)

wouldnt the Carrera exclusive design wheels be lighter because they are forged and have less material? There’s a lot to the spider wheels. Idk, just asking.

Removing the backseat under cushions/belt receptacles gives you 7.5lbs (very easy to do) and removing the back seat rests (which I haven’t been successful at) should probably total all that to about 20lbs.

.......Since my car will be tracked every week......
Seriously? I have never met anyone who tracked their car every week. Do you live in some dedicated home community where there is a race track actually in with the homes like the one next to the BMW Performance complex in Thermal, California?

If you ARE going to the track weekly, you should be buying a dedicated track car, not trying to get 100 lb out of a 992 while at the same time saying consumables are too expensive. Sorry, you come across as a person who has very limited real world track experience but perhaps a lot of dreams. Us Old Timers who have been doing track days since the 90's know the folly of using an expensive street car on a race track on a regular basis. What you are proposing is silly because you will wind up with a lousy track car and a crappy street car trying to do both with one vehicle.. 100lb is not going to make a bit of difference in your lap times. I have seen - more than once - professional factory race drivers like Bill Aubrlen and Hans Stuck put three other large men in four door M-cars (an extra 600 lb or more) and absolutely smoke everyone else on the track driving solo in the same model cars during demo days. That extra weight didn't matter.
You have much to learn, grasshoppa.

That said, if your set on it, real lightweight CF racing seats would be the biggest weight loss for the money and much better supporting you in high 'g' load corners.

Racer
with all due respect, when I race street cars I beat all of the “race cars” (outside of open wheel and gt3 cup cars) on the track. The Miata’s, spec boxters, tuned **** boxes etc are all slower than a stock 911 on the race track. I’ve been tracking my cars for years lol so I’d say I’m probably a better driver than you “grasshopper”. I want a do everything car and I’m always faster without a passenger around my local race track, so yeah weight ****ing matters. We have track days every week di** head. So yeah, I can drive every f***** week. Get your crap together and stop commenting nonsense. Go drive a Tesla that’s 600 lbs heavier since you don’t care about weight. Liberal

All of the cars that are lighter than a 992 are either much slower or more expensive. Use common sense please.

Whenever I say something that's true on this forum many of the people get butt hurt and call me names. But they never address the true stuff I say and therefore, makes y'all look like you're turning to defense mechanisms because I said something you didn't like

From PCNA website:
Carrera:
Curb weight 3,354 lb
Carrera S:
Curb weight (Manual) 3,298 lb
Curb weight (PDK ) 3,382 lb
Carrera T:
Curb weight (Manual) 3,254 lb
Curb weight (PDK ) 3,338 lb
Of course some variance depending on options selected, but based on this we can see Porsche claims to have saved around 44 lbs on a T from the S regardless of transmission, and only 16 lbs from a base Carrera if comparing the same transmission. They claim the weight saving comes from the lightweight glass, removal of the rear seats, and less sound insulation. I'm not sure why a C2S weighs 28 lbs more than a C2 but I'm assuming whatever it is adding that weight the T doesn't have it, since we can take from these quoted weights that the PDK adds about 84lbs.
What I'm getting at is you'll probably need to take drastic measures to remove 100lbs. Will it be worth it? In my opinion 100lbs should be enough to make a difference in how the car feels on track but definitely not night and day. My track experience is primarily with my 3850+lbs W204 C63 coupe. It's really too heavy to be on track but lots of fun to rev out that engine properly. I would love to remove some weight from it to improve the experience but to take out 100lbs based on what I've seen other do would require many things like stripping out all the sound deadening, back seat removal, deleting the panoramic roof, removing the power seats for fixed buckets, etc. Totally changing the car. Might be worth it but instead I decided to leave it alone and go for the Carrera T, the power to weight is similar but I think driving a 3250lbs car vs a 3850lbs car will be a totally different experience on track.
