I did mine pretty early solely because the OEM rotors were wearing like a vinyl record. Both the pads and rotors still had plenty of material—it was just a bad wear pattern. I went to Girodisc pads and rotors and have had them on happily ever since.

Pros: happy with Girodisc

Cons: bad wear pattern

I have been running giro disc on my 991.1 GT3 with pagid rs29 pads. 15 days and only about 0.5mm wear. These are the only option for PCCB conversion.

Pros: low wear, only option for conversion

I had similar issues with my girodsics when I got them. The bigger issue was the rotors were hitting the top of the caliper and SCREAMING even when I wasn’t braking. I got in contact with Girodisc and they sent me some more spacers to push the caliper away from the rotor a bit more.

Pros: manufacturer provided solution

Cons: rotors hitting caliper, screaming noise

On the way back it started shuttering bad while breaking, especially down hill. I took it back to the place that did the brakes and they said front rotors were overheated. The parts are TRW (pads and rotors).

Cons: shuttering bad, overheated

Vehicle: Ford Transit

Mileage: 3000 km
