718 Cayman S PCCB advice
Discussion
Hiya
Could anyone with experience share their opinion with me.
I've got a Cayman 718 S on order for delivery later in the year.
As part of my original order I spec'd PCCB brakes the car. My logic been I'm going to use the car on a track 4 or 5 times a year so the upgraded brakes would be a good and desirable thing.
However after looking at reviews on the net I've seen people advice against this on the basis the standard brakes are more than up to the job and that the PCCB are a better option if only using on the road due to their pretty quick rate of replacement if tracking the car?
TBH I'm not 100% on replacement costs of PCCB discs and pads but would appreciate advice on it.
I don't lock my spec till August so no major rush
Thanks Jamie

Replacement disks are £2000ish a side if I remember rightly and need doing when scored, cracked or worn. Pads need to be replaced when around 50% of life is left to ensure heat dissipation and minimise disk damage.
The general consensus is that steel brakes are more cost effective for the track, however PCCBs are larger than the standard brakes (unlike on the GT3/GT4). If you want the larger brakes you could swap the PCCBs for steels once you own the car, this has been known.
If you're a heavy track user I'd buy PCCBs and swap the disks/pads for steels. If it's occasional track use I'd stick with the standard brakes unless you have deep pockets.
Personally, I wouldn't have PCCBs on anything other than a GT4 or Spyder in the Cayster range given the purchase and replacement costs in relation to the vehicle cost/value.

From my own experience, and the consensus of what I've read, the PCCBs do offer notable benefits, whether for road or track use.
However, for extensive track use (and 4-5 days a year isn't really extensive), then many people will select the iron rotors. This is because when these wear out, they are less expensive to replace, but more likely, they will fit an aftermarket option.
For mainly road use, I'd prefer the PCCBs. You get lower unsprung weight, improving handling and ride, no brake dust or corrosion, superb performance and probably 100,000 mls plus life. On GT3s and GT4s they do add resale value, but maybe not so much on a 718.

While lower unsprung weight is always a good idea, I did a back to back with my 981on steels and one on pccbs at the PEC and I found precious little difference - far less than a change of tyre brand or with /without PASM for example.
And when I bought my car, I could buy cars with or without pccbs, but otherwise to a similar specification for the same money.

But the weight difference between one wheel type combined with a particular tyre brand can easily match or exceed 3 or 4 kg and is a far cheaper route to follow. In addition that approach yields a far greater reduction in gyroscopic effects because wheels and tyres have a much bigger diameter than discs. This was analysed in great detail in a previous thread.

^ exactly. PCCBs are only of a weight benefit if you're chasing it in other areas too IMHO. It would be interesting to know what the weight difference is between the stock 718 disks/pads/calipers and the PCCB versions. Is it really 4kg per corner? That sounds a lot.Twinfan said:

A single replacement disc is around £3800 ~ from Porsche, as I enquired about them on mine before committing to them. The PCCB disk should be good for the life time of the car and its only the pad which will need replacing at 50% wear but that's only to stop excessive heat build up. They should be fine for a few track days, as long as you take the time to properly cool them down afterwards.
My main reasons for choosing the PCCB's on my 981 was they offered better initial bite and peddle feedback over the steels, as I back to backed two cars.

My instructor at the PEC was insistent on a cool down lap. My main reasons for choosing the PCCB's on my 981 was they offered better initial bite and peddle feedback over the steels, as I back to backed two cars.
Agreed they have more initial bite - but on the Road, if you heel and toe LESS is preferable and both types could be far heavier with advantage.
Had PCCB's on my 981 (someone else paid for them!)
Pros
Wheels dont get covered in brake dust and stay cleaner for longer
Great on the 2 track days I did; Tyres melt long before the brakes do
If looked after properly they will do 100k+
Cons
If they go wrong it gets expensive quickly
When I traded the car the dealer spent an hour checking they were ok; clearly demonstrating hey are an expensive issue to sort
Some buyers were frightened off the car because of them,
Save the £5k thats a lot of diss/pads/tyres/extra options.

On several track days I've been to, there was at least one occasion where the red flag came out and there was no chance to do a cool down lap, worst if you happen to be approaching the pit entry at the time.That's partly why I went with steels for tracking.
