To be honest, get the aerokit if you like the look. If not, don't get it.
Don't make the decision on the aerokit based on track performance...
What you should not do is get an aftermarket GT3 wing on your GTS and drive that on the track. That wing has real downforce and you will be lacking the downforce at the front of the car and get yourself in quick trouble.

I went with:
Lightweight buckets, lightweight glass, RAS, lithium battery and aerokit.
I added:
Giro disc brakes, Ferodo pads, Bilstein coil overs, Goodyear Supercar 3 R tires, Cantrell Motorsports roll bar, and Schroth 6 point harness.
Couldn't get a GT3 allocation. Poseur, perhaps, however I can tell you that it's much faster than my old 2015 GT3 and at least as fast as my previous 2019 GT3. Great car!

Is there any data on the actual downforce produced by an aerokit car vs non-AK? My guess is it's not that impactful, but it's hard to say for sure.
It seems like Porsche is playing some games with the lightweight package's weight savings claims. The package 1) eliminates rear seats, 2) includes lightweight glass, 3) includes RAS + LiFePO4 battery, 4) reduces sound insulation, 5) switches to bucket seats. And they say it saves "up to 25kg". link
Porsche says the LiFePO4 battery weighs nearly a third as much as the standard AGM battery, at 12.75kg. That means the standard AGM battery weighs ~38kg. That's literally all of the 25kg of weight savings right there, so either they're being very conservative with their weight savings claims or you can get 85+% of the lightweight package's weight savings by just optioning RAS.

Edit: Upon further thought, I think the actual RAS system also adds a bit of weight so that probably explains why the full weight-saving claim about LWP is accurate even if the battery change itself saves 25kg.

Thanks to the advanced battery technology and power density, 20 per cent less space is needed and the weight of the on-board battery is reduced by more than half, from 60 pounds to 28 pounds.
So the the Li-ion battery saves 32lb / 14.5kg.

I went with the OEM Porsche Exclusive 5 spoke wheels. They are forged...and easy to clean!

From the turbo-S press release:

“The service life of the lithium iron phosphate battery is 2.5 times that of a conventional lead-acid battery, but it only weighs approximately a third as much, at 12.75 kilograms.”
https://media.porsche.com/mediakit/9...weight-package
So the regular battery weighs about 38.25kg and the lithium iron phosphate battery weights 12.75kg. Why wouldn’t that mean the lithium battery saves about 25kg?

Not sure how to square that with this:
“The service life of the lithium iron phosphate battery is 2.5 times that of a conventional lead-acid battery, but it only weighs approximately a third as much, at 12.75 kilograms.”

Approximately is the key word here, and it seems that they were generous in with their approximation. In the turbo-S press release, they have hard numbers with 60lb and 28lb, I would tend to trust these more than the "approximately a third" statement.

Beyond what's been mentioned, consider a set of light track wheels in 19/20 or even 19/19. Consider getting 5-lug as CLs are a hassle if you're swapping often.

The 12.75kg is consistent with the 28lb.

Does anyone know how much the RAS system by itself weighs?

Get the LWBs if only to hold you securely in the car, otherwise the single biggest GTS performance spec is… ‘seat time’. You won’t be ‘racing’ anybody but yourself so grams / ounces / pounds are meaningless for gussied up street cars. Focus on your technique since you’ll never ever notice 20lbs of an Li battery or lightweight glass.

992 GTS Center Radiator
Are people seeing their 992 GTS come equipped with the 3rd, center radiator? If not, anyone go through the process to have one installed?
Many thanks!

Alright - we all know the GTS doesn't really compare to the GT products but many of us can't get a GT3 and a 992 GTS is the next best option.
Debate for this thread - what is the best way to spec a GTS for performance on track! Specifically, would you take the lightweight package or the aerokit as those two conflicts (can't spec both).
Options:
1. Lightweight package: Bucket seats, RAS, Lithium battery, lightweight Glass, reduced sound deadening, GTS aerodynamics, etc.)
2. Lightweight glass + RAS + aerokit
I took out the PCCB and PDCC as those are not available. PCCB would be no-brainer, PDCC is another debate.

Get whatever spec you desire. But I have some thoughts:
- NO 14 way seats, get sport or bucket seats
- PDK, but I guess manual ok if you're a boomer
- RAS makes the car feel much more nimble
- Extended range tank. These cars EAT gas at the track.
- PDCC if available, yeah it's better
My GTS also has front axle lift, which I constantly use, and a glass sunroof. Car is bonkers fast enough. I'll never be able to drive it to its full potential.
Swap the brake fluid for high temp fluid before that first track day, that's it.
