Not at all. I was just in the garage tinkering around and admired how "polished" they look - like a mirror - and the car has been siting idle for about a month. My 911 has PCCBs and I'd say the GiroDisc look even better. Very happy I made this upgrade. They do dust, but no where near the amount that the OEM rotors do. They also do not oxidize very much after a wash. I paired them with EBC Red Stuff which also dust very little. Great performance combination for the street.
718 S GTS GiroDisc Rotor Install - Review
Just thought I'd post my experience/review of the Girodisc Rotors for 718 S/GTS models.
Firstly, the larger GiroDisc are not any lighter than OEM but with the alloy hats the weights come out very similar so there is not really any weight penalisation. If you want to go lighter carbon ceramics seem to be the only option.
I used our regular bathroom scales so not the most accurate but you get an idea:
OEM Front 330mm Rotor 9.7kg, GiroDisc 350mm Front Rotor 10.3kg (measured ~ 353mm)
OEM Rear 299mm Rotors 5.6kg, GiroDisc 325mm Rear Rotors 5.7kg (note these measured closer to ~322mm)
As far as braking goes there might be a perceived psychological improvement but otherwise no issues and I have not noticed any fade even after 5 or 6 laps on a short track. I did have to get my workshop to adjust the rear E-brake so the hub tolerances must have been marginally different.
Asthetically I think they look nice, particularly the anodised alloy hats in contrast to the OEM Porsche rotors which always look rusty.
Here is what's in the kit including front and rear caliper spacers and longer bolts:

Just to update, looks like I've destroyed my Girodisc rotors a bit prematurely.
Not saying it is a fault of the rotor but perhaps the fact that my car is 90%+ used on the track in time attack/supersprint so perhaps very hard on brakes.
Nevertheless these rotors probably lasted one and a half pad sets, although you can see from the photos below I left my last pad set (DS3.12) a little too long so that probably also did not help the rotor.
Essentially the pads have worn very unevenly and carved almost a 2mm groove along the inner circle of the rotor compared with the outer circle due to the bottom of the bad becomming thicker than the top of the pad.
I've posted these photos in a thread on the DS3.12 pads as a follow up but thought I'd put here as well.

What I've learnt is that pads wear very unevenly and to check the pads more regularly. My workshop also said I should rotate the pads. Not sure if this is normal or not so hopefully others can chime in.
Here are the photos of what's happened so maybe others can also learn from my experience. You can really see how uneven the pads have worn.
These are the front DS3.12 pads:

And the rear DS3.12 pads:

This shows the horizontal taper:

And now the vertical taper where the pad is thicker at the bottom than the top, which is what's worn the inside circle of the rotors:
