Brake discs R1 Concepts or GiroDisc

Absolutely love my girodiscs. I’m on DS2500s which its time for an upgrade to a more aggressive pad, but they’ve held up through quite some heat lol.

Went from OEM to Girodisc 350mm. All street, no track. By far the best upgrade I have done to my 991.2 C4.

Go with the Giro's and leave them on permanently. Better cooling and braking and cheaper to replace just the discs (2 piece rotor) on future replacement.

I’ve ran r1 concepts drilled and slotted rotors for like 3 years now with stoptech pads and never felt the need to upgrade higher than that for just dailying/spirited driving

I run r1 concept rotors with ebc red stuff pads and they work great for me

I installed R1 Concepts slotted on my 13 R/T years ago. They are better than the brakes that came from the factory.

I went with R1 concepts. Really good brake rotors and brake pads so far. I’ve had their regular ones and just switched to drilled and slotted. I’ve noticed an improvement in braking after driving for a while as the brakes don’t heat up as much. But it depends on your driving style. R1 concepts kits also come with hardware if you select it which would help because the oem hardware get warn out after a while.

I have used R1 concepts geomet drilled/slotted rotors twice. The pads were pretty dusty but worked well.

I just did mine brakes & rotors on my 2019 1.5 and all parts from R1 Concepts, drilled & slotted. Feel so smooth!

I use them. Hard to say if they’re better than stock but they’re cheaper
