Brake discs TRW or GiroDisc
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
Replaced with girodisc two piece rotors. They are great!
Pros: great performance
Vehicle:
Chevrolet
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
Vehicle:
Porsche
I'm using a set of Girodiscs all around with the AP Racing calipers and it's a fantastic combo.
Pros: fantastic combo
Vehicle:
Porsche
I have them on the Brembo front bbk on my e39 N5 and really like them for street use.
Pros: good for street use
Vehicle:
BMW
Have girodisks on my turbo 987.1 s, love them. Much better feel and braking performance
Pros: better feel, improved braking performance
Vehicle:
Porsche
why not switch to 2 piece giro disc slotted rotors or ap racing j hooks
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
Rotors (Girodiscs 2pc) have already been confirmed to be seeing 1500F temps. Cracked annd needing replacement after 10-12 days on track.
Cons: cracked, short lifespan
Vehicle:
Volkswagen Golf
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
