Good article. I think a lot of conversations are people talking past each other. A person who doesn’t track his/her car and wants the look/exclusivity/performance/etc. will look at the choice much differently than a person who goes to the track 5, 10, 15 times/year. I am disappointed that PCCBs are not as indestructible as was implied when they first came out, but even then the intent may have been aimed at folks who won’t track their cars. But not so disappointed that I didn’t spec them :-)
i am willing to sacrifice 5-6 lbs per wheel in weight over the AP racing competition BBK to lower the cost of my track habit.

With all due respect saving a few pounds is no substitute for track time. Far too many people spend $’s on their cars needlessly.....

Totally agree. As I mentioned previously, if you are not a track junky, they will be fine. For those who track often and don’t want to fund Porsche’s next generation 911, a whole industry has sprung up around providing steel rotors that fit the existing PCCB calipers and pads. Another factor is the choice of pads is limited for PCCBs. I like to have choices.

the rotors are two piece and when you wear them out you just replace the disc ring, not the entire rotor. You will have to change pads but would want to put in a track specific pad anyway. I run Girodisc on my AMG, AP does not support Mercedes yet.
Changing rotors is really pretty easy. You keep the fluid line attached to the caliper so no need for brake bleeding. I just changed the front pads and rotors on the AMG and took about two hours including beating the shaft out of the old ones to release them from the hub. Use a lot of anti-seize on the hub to keep this from happening.

FWIW, a buddy of mine went through more engines (2) than PCCB rotors on his 991.1 GT3 after about 7k track miles (not total miles, but track miles).
I'd imagine the new Gen IV PCCBs will be even better.

The Gen III PCCBs on the 991 cars were very durable and sturdy, even for extended track use. The 918 had the Gen III PCCBs and the were fine on that car after extended track duty.

I don't have confirmation either way, but I can't imagine Porsche not improving the ceramic rotors from one generation to the next. The PCCBs on the 992 models are at least bigger than the 991 models, if nothing else.

One thing mentioned in other threads that I wish I would have known (but may have changed for 2021?), if you go with either of the 4-ways you do not get the automatic tilt of the passenger side mirror when putting the car in reverse.
I have the S+ 4-ways and they are fantastically comfortable, but the lack of an auto tilting mirror to avoid curb rash is a bit of a head scratcher.

I am in the process of configuring my 992 turbo and am also trying to find out the weight difference between the 4-way and 18-way seats. Theres seems to be a lot of anecdotal information floating around. Porsche claim a 66lb (30kg) weight saving for the "light weight package" on the 992 turbo-S, which comprise of lightweight front bucket seats, rear seat deletion and reduced sound deadening. Further, a chap weighed one of the 18-way seat on his 991 Turbo-S at ~63lb. So I doubt the 4-way seats by themselves can account for 60lb.

For me the 4 ways don't work as I have long thighs and definitely need the support of the thigh bolster. On the other hand I prefer the manual steering wheel adjustment over the power one. The power one is too slow :-)
Guess even Porsche can't satisfy everyone with the bespoke option strategy :-)

Since I just got my car, I’m not about to pull out my 4 way seats and weigh them. I will say that I don’t miss 18 way seats at all. My sport plus seats are very comfortable and having the extra bolstering and sport Tex insets really holds me in nicely when driving aggressively. I weighed my car and with an empty tank of gas it is 3300 lbs. That is with the PDK. When Porsche says it’s 66 lbs lighter, they don’t reference the baseline. Bottom line, I am happy with my build and have plans to get to 3200 with an empty tank of gas.
.Since I intend to use my car on track a fair bit, weight matters to me. I am just weighing between the practicality of the 18-way (my wife will also be using the car) vs the weight savings of the 4-way.

the ONLY reason why anyone would say 4way is better than 18 way is 1)ego 2)ego 3)ego ... not a surprising pattern here on rennlist.
