common sense. As said, you know the areas where all cars can shed weight. You just want to start fights as usual.

I think the engine is pretty heavy. Start with that?

You know… you can own more than one car. There’s no way to lose 100lbs without compromising its utility as a daily driver.
If you really want to lose that weight, here’s how you do it at your own risk. To be clear, these suggestions will compromise the safety systems of the vehicle to save weight.
1. Remove/front and rear bumper beams. Don’t get in accident, because your insurance company won’t like this one bit.
2. Ditch the A/C compressor and condenser. Not necessary for most of the year.
3. Strip the interior bare. Get rid of the back seats and related hardware. Pull out the carpeting and insulation. Remove all plastic trim and the headliner. Door cards go as well.
4. Replace your OEM seat with a carbon fiber bucket. Ditch the seat rails and have a fixed bracket mount to the factory points. Don’t bother with a passenger seat, because your significant other won’t want to ride in this car when we are done.
5. Airbags are just dead weight. They all have to go. You’ll probably have to terminate them or use PIWIS to make the faults go away.
6. Under the hood, remove all of the plastic around the frunk and the tub. Your 911 will no longer be suitable for the rain, so you might as well pull the wiper motor and windshield washer hardware.
7. Replace your OEM battery with a lightweight battery. In the old days, I would say you could remove the alternator and run total loss electrics, but these modern ECUs and fuel injection systems don’t like that.
8. Your 992 will protest the PCM removal, but you can ditch all of the speakers. You don’t need them. If someone has a workaround, let the OP know.
9. Most aftermarket carbon fiber offers precious little weight savings, if you can find really lightweight dry carbon pieces, go for it, but don’t buy the stuff that uses fiberglass underneath. It’s really hard to get weight savings over the aluminum pieces with the cheap stuff.
10. Windows. Everything gets replaced with plastic. Astounding weight savings getting rid of that glass. With the wipers removed, you won’t be scratching anything up. Buy a case of plexus. You’ll learn why. Ditch the power window motors. Yeah, you might regret having 86’d the air conditioning, but you will be light.
11. I would normally suggest a lighter headlight fixture, but don’t know of many good alternatives. To pass state inspection, you will need lights. You can do everything that I mentioned so far and still pass inspection in many states.
12. If you’re not worried about state inspection, it’s time to ditch the cats and do a lightweight exhaust system.
13. You might be thinking “Why hasn’t he mentioned wheels yet?” Well, the OEM wheels aren’t much heavier than aftermarket DOT alternatives. So, might as well skip the DOT approved wheels and go for some carbon featherweights. You will have to change them out for DOT wheels for inspection depending upon the sophistication of your state inspection process.
14. You can potentially save weight by ditching the active rear spoiler, but pick your aftermarket alternatives carefully, because the cheap stuff is invariably heavy.
15. Cages add weight, aren’t a great idea on the street, and may even cause a car to fail inspection in some states. That being said, if you’re this far, you have stripped out all of the safety systems, so your call.
16. You can trim a few more pounds by ditching the PASM suspension for the aftermarket, but weigh them first. Lighter arms for a 992 will probably require fabrication.
There you go. If you do the above, you’ll save hundreds of pounds. The car will be quicker and absolutely miserable on the street. 😜
… and this is why it makes sense to own more than one car. 😁
If I missed anything, let me know. While I created this list tongue in cheek, I basically listed a bunch of things that I have done in the past when I was young and stupid. Lol

If the OP is serious, he needs to speak to @Robert Linton and read through this thread to see Robert's work. https://rennlist.com/forums/991-gt3-...reduction.html
Impressive stuff.

Why are these not further apart given that the T has a lighter battery (irrespective of RAS choice), no back seat and lighter glass? Is there anywhere that the S saves weight over the T?
As far as weight savings ideas -- base stereo perhaps? Subwoofers are heavy...

Driving a 992 with PDK on a track is like using cheat mode against a Miata.
I tracked a race prep Miata for a day and I was exponentially faster in my M2 Competition. If he's conditioned to a PDK 992, there is no way he'll want to go to a Miata.
Personally, I think most weight loss measures are going to be self indulgent. I went on a major weight loss plan in my 993. I removed the stereo, converted it to RWD, put in an RS steering wheel, lightweight flywheel and RS clutch, lighter weight mufflers and lighter weight wheels. I dropped about 200-300 lbs of weight. The two things that made the most meaningful difference were the lightweight flywheel and the wheels. Static weight loss is overrated, IMO, unless you are talking a few hundred pounds. Rotating weight and unsprung weight are the most impactful. Removing weight from the rear with an exhaust is worthwhile as well.

It's hard to reduce the weight of these cars substantially, while maintaining streetability, without some serious cash outlay.

It is better to be silent and look like a fool than to speak and leave no doubt on the subject.
