Someone on Rennlist performed a very detailed weight comparison when converting a steel equipped car to PCCB and you are right. The weight savings of the PCCB disks are largely offset by the larger calipers to the point where the difference is measured in grams, not kilograms.

I have to laugh when people state that the difference in un-sprung mass transforms the steering of these cars. Smoke and mirrors comes to mind.
As i suspected. I imagine the steering does feel different on the PCCB cars due to the lack of gyroscopic effect, however overall vehicle weight i agree will be negigable compared to a steel rotored car.
Slightly off topic but i remember fitting a set of forged Volk CE28N wheels to my impreza which were circa 7.5kg for an 18" wheel.
The difference in steering feel was instantly notcable as was the way the car picked up under power.

The mass reduction of the carbon discs improves steering because the center of mass is closer to the steering axis. Less gyroscopics and that.

The bigger the discs the greater the influence, I'd imagine it to be fairly small on a 987 Cayman though.....

Agree, i imagine by time youre talking 991 GT3 monster 410mm jobbies, the effect is quite considerable.

From the Rennlist post.




https://rennlist.com/forums/987-981-forum/971809-9...


As for the weight of the components, here we go,

Front:
- PCCB calipers/pads (set): 11.9 kg
- Red calipers/pads (set): 9.1 kg
- PCCB disks (set): 11.4 kg
- Red disks (set): 18.4 kg

Rear:
- PCCB caliper/pads (set): 9.2 kg
- Red caliper/pads (set): 7.6 kg
- PCCB disks (set): 11.0 kg
- Red disks (set): 14.0 kg

Total weight - caliper/pads + disks
- PCCB: 43.5 kg
- Red: 49.1 kg

So, from an unsprung weight point of view, PCCB saves 5.6 kg total for all four corners. The PCCB front disks only weigh 62% of the front steel disks, but much of the saving is offset by the larger/heavier 6 pot calipers that comes with PCCB.




The undramatic weight saving is due to the the jump from 4 to 6 piston calipers on 987 model cars when going from steel to PCCB. You get a much better weight saving on a GT car as they use 6 piston callipers for both steel or PCCB.

I'm sure there was a topic on it recently but I cannot for the life of me find it. Did someone say that the short shift option on the R solved the problem with the gear linkage cables coming loose / snapping?

I think that was the Cup cables...

I’ve got the Numeric cables and shifter however not on the car. When I spoke to RPM Technik about this last they said they had not had a cable failure on a car running the OEM Porsche short shifter... hence the Numeric setup isn’t yet fitted

Damn. It amazes me they don't have a non third party solution other than just replacing it over and over...

Picture of R on the drive



I love Peridot Green on the R. I respect anyone's colour choice but I've done all the black, white, grey ("it's a traditional Porsche Motorsport colour", "it's a wolf in sheep's clothing", "think about the resale value", etc.) colour selections and really wanted something that stands out this time. Extremely happy.

Its almost certain when you see a Peridot 987, it will be a Cayman R. As opposed to a PTS base car or Cayman S.
It was the launch colour for the model and IMO the best colour to own an R in. (Although i do love white, yellow and red biggrin)

there are a few 991 and new cars about in this now. But it only works on the R imo.




my old car, looks great clean, looked like pea soup when dirty :-)

It is an odd colour, I think it looks perfect on the R but have yet to see any other car that it suited. Some of the other Porsche greens look great on other Porsche models, but not peridot. Like a viper green 911 which I think can look mega.... although controversially I don't think that green suits the R. boxedin

Does anyone please have a photo of their R's interior with Alcantara pack/trim on gear selector and handbrake?

What original options were available for non-standard console storage cover? Just "Porsche" lettering or logo also?

Has anyone got a list of all the original UK options with prices please?

The alcantara wheel is great, love mine but I do wish the center marker was coloured.

Alcantara center console is nice, I wish mine had that too.
