Re: Cayman GT4 & 718 Spyder -- Pistonheads review
d997h:@bluelines, hmmm, it is "next week" already, isn't it ? You could post some pics already, even before giving the car to detailing, I do not mind...
The car is back from the body shop. The front and the hood have been resprayed. The rest of the car polished and ready. They noticed that the front brakes were soon gone so I will get new ones. Plus some warranty work on the engine/gearbox. They wanted to do that now to ensure the car is 100% and that all work is covered by the warranty. Sooo, long story short, another week before I can pick it up.
Vorfreude, heh

4trac:Front brakes shot?? Is it that high km, or do I just not understand how Swiss roads destroy brakes?
No, neither. The use of „soon gone“ was maybe a bit exaggerated. The brakes were not that bad, but I got a new set anyway. Same with the tires, they were ok too, but they threw in a new set of Michelin Cups. Corona generosity

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
Question about PCCB vs steel on the 981 GT4:
I believe the steel brakes are more than up to the job for a car that might see the track once or twice a year, and that PCCB will give off less dust (and they look cooler ), but any other arguments one way or the other? Looking at three cars right now, one with PCCB, the other two without. Otherwise, specs are similar. Car would not be a DD, so not too worried about replacement cost on the PCCB. The car might be driven periodically in cold weather (up to -15 C), are there any issues with PCCB in the cold?
Thanks.

Imo, PCCB give a better break feeling and steel breaks should be the choice for track days taking into account replacement cost. PCCBs always are at risk to get damaged through stones and debris on a track...

Go with steel.
PCCB are like marshmallows when first applied in the cold.
Most of my cars have PCCB. If I come back from Whistler, and it's raining and/or cold, on the first exit I take the pedal pretty go all the way down without stopping. They all do that.
Only go with PCCB if you like the looks of the bigger brakes, and there isn't a premium in picking a car with PCCB.
Unless a car come standard with PCCB, I would not pay extra for the PCCB option. And I already mostly checked every option box when ordering.

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
spudgun:Bit more noisy in the cold, and if you visit the track: don’t end up in the gravel. If you see a man crying in a gravel trap, he probably has PCCB.
That's an easy assumption, he might just be trapped full stop.

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
Thanks for the replies. I think I'm leaning toward steel.
Is anyone aware of the strut tower 'issue' on the 981/991 cars? There seems to be a relatively low level of occurrences, but apparently the strut towers are made of cast aluminum, and can break under hard cornering or from hitting objects or potholes. Porsche refuses to cover this under warranty even though it seems to be a design flaw. Repairs are in the neighbourhood of $20K USD. Cause for concern, or likely overblown?

Yes, I have seen a few posts about the strut tower failure on other forums. I doubt this issue can occur under hard cornering only. If it does, then there was already structural damage due to hitting a pot hole, curb or other object.
Some people claim the strut tower is a design flaw, but if it was then I had expected it to be fixed on the 718. It is not. The part numbers are identical to the 981.
It is anyway not a problematic repair. The part costs CHF 300, is riveted to the chassis and can be replaced by your nearest Porsche garage.
The owners who did not get this covered under warranty seem to have had other damages to the car due to hitting objects. Hence Porsche claimed it is not an issue with the car, but with the driver 
Not a concern IMHO.

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
Joe, that has come up on the internet about two years ago . At the end it was established that the ones who had it had lowered their cars a lot + hit some curbs very hard .
It is a non issue .

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
if you lower the car and have the possibility for such failure, that is not normal.
the suspension is adjustable and the car should be reliable in all configurations.
now hitting a pothole or a curb is a different story.

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
The only time I have ever seen that happened in person was when I was at Pikes Peak, one of the GT4 flew off half a cliff and landed in a pile of rocks (not me).
Outside of that, think maybe I saw like 3 of those in pictures on the internet.

I know that this is a GT4 thread, however, for what it's worth, 5 years of ownership of a stock 981 GTS with DD and track driving and no issues whatsoever regarding this area.

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
If there is no premium for the pccb then get those ( as Whoopsy mentioned). No dust and will pretty much last a lifetime. Including pads. If you don’t track it. My 997s had them and they were the best part of the car. After almost 200 k miles the pads looked to be at 50%. Just my 2 cents.

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
I think both mid-engine and rear engine platforms are susceptible to this. I always try to avoid hitting curbing hard at the track (particularly on the loaded outside of the corner) for this reason. Not sure if the 992 has addressed this or not...
It also increases risk a bunch if the car is lowered (even if using the stock adjustable spring perches with the GT3/GT4)...

Re: Cayman GT4 & 718 Spyder -- Pistonheads review
JoeRockhead:Thanks for the info guys. From what I read, it seemed like in most cases there were extreme loads or impacts. I would think that non GT4 cars would also be susceptible to this but haven't heard much about that.
It really is.
If it isn't and was a design defect, Porsche would have issued a recalled and fix it properly. After all, the same design is used on their race cars which have raced 100s of 1000s of laps all around the world without problem.
If it isn't working on their race cars they would've changed the design a long time ago.
