My goal was the ultimate track gts, and I don’t regret the RAS or PDCC. I think the main theme here is people becoming attached to their own build and defending it.
lithium battery alone seems to make the options worth it, lowers center of gravity and all that. For similar reasons I did the sun roof delete and manual seats.
After chasing ‘23 992’s without RAS/PDCC on track in my ‘23 92 that has them… I would spec my car the same every time. The grip and stability at the limit is incredible.
HOWEVER you build this car you’ll fall in love so don’t lose any sleep.

I gave this thought too. However, the replacement battery, and I believe it has to be that specific one, is $2,500. There are lighter Li batteries that seem to hold up better for $1k. It's one of the things I will swap out to reach my 100lbs loss goal which would've been some 30lbs harder had I ordered RAS. If you're going to track the car, it's worth considering. I already have a track car but though it through anyway and my conclusion was to nix it on the basis of the battery, the additional weight of the system and adding one more thing that can break, not to mention that I rather work on becoming a better driver than fall under the illusion that I'm better than I really am because the car is doing my work.

Let's play a fun 992 'technology' game shall we?. Here's a quiz, spot the similarities...
You want 'analog', go drive an Elise.
- VTG - (Active) Variable Turbocharging Geometry
- PASM - Active suspension
- PADM - Active motor mounts
- PSM - Active stability management
- PTV - Active torque vectoring
- PSE - Active exhaust
- PDLS+ - Active headlights
- VarioCam Plus - Active valve timing and lift
- RAS - Active rear steering
You want 'analog', go drive an Elise.
-VTG is tech, but it makes the motor seem more like N/A, so I would say this is tech that increases “pureness” in that way.
-Pasm- agree, don’t need it or want it on my 911
-PSM- helps me not die and mandated, so…call this one out of scope
-PTV- agree and don’t need or want it
-PSE- agree don’t want or need
-VVT- Not really perceptible so no impact on “pureness”
-RAS- Only option on the list I can deselect to increase “pureness” so out it goes. If I could go dodge viper on all the other stuff I would, and would happily almost hit a tree accelerating from every stop sign.

I think the car behaves very nicely on the street with the RAS. I think if that is your intended use for the car, or at least predominant use, it would be a nice option to have. Easier to maneuver at slow speed and park and maybe smoother on the high way.
I think it would probably be a lot of fun for the occasional track day but my mind has a hard time trying to figure out how the RAS +/- steering angle and the slip angle of the tires would work if you're really hooning it at the track.
I have SPASM on my S and I think it corners pretty flat. I race a M240iR on adjustable sways and MCS setup and it has more body roll than the 911. Depending on your handling preference sometimes it's nice to have a little roll feel as you load up the tires.
If I was going to spec brand new RAS yes, PDCC no.

Even though it's a small angle, it does make a noticeable difference especially on fast sweepers. I'm sure it's a great contributor to the speed records of newer GT cars on the ring. However, for those who don't track, don't track enough, or do tighter tracks. the value is just not there and the risks are too high. Read the thread below. Some people with defective batteries (the Li ones that come with RAS), have been without a car for 4,6 and 8 months. Not a great way to enjoy your freshly spent six figures for the sake of better behavior on the street IMO. If that's not convincing enough, do a search for RAS failure. Not cool either.

Neither is a must have.
PDCC is amazing in Cayennes. The 911 in stock form turns flat and doesn't need help.
RAS is a polarizing topic that has been discussed ad nauseam. Do a search. Bottom line: the primary benefit is easier to park, easier to U turn and faster in sweepers at the track. The drawbacks include a mandatory $2,500 battery, extra weight, and one more gizmo to break and to make the car drive you instead of you driving the car.

The RAS is great for tight parking lots and making U-turns on residential streets. Additionally, it is excellent when making fast lane changes. I had to do that on a couple of occasions when another car swerved into my lane and I was able to make a very quick lane change at 80+ mph w/o upsetting the balance of the car. It was super stable even though I had to yank the steering wheel very abruptly. I've also had zero issues with my lithium ion battery for over 2.5 yrs - and this included not driving the car for a week to two weeks at a time during the pandemic without ever using a battery tender.

Can anyone elaborate on PDDC and car sickness? I get car sick pretty easily and I'll take Dramamine on track days. Would hate to one day get a car with something that for some reason makes it worse.

I’ll also say that PDCC can’t entirely erase suspension stiffness of GTS. You will suffer from bumpy roads, where standard PASM C2S rides really good
