Brake discs Raybestos or GiroDisc

Raysbestos Street Performance rotors are excellent. They are high-carbon and better able to manage heat and resist warping and cracking than ordinary grey iron rotors.

Replaced with girodisc two piece rotors. They are great!

Raybesto Elemental rotors. You wont have to deal with rust on the hats anymore.

I'm running Raybestos R300 slotted rotors and Powerstop Z23 pads on my 4/2 Brembos, from Rockauto. No complaints or squeals. Holds up really well with repeated heavy braking in the twistys too.

I have personally used Raybestos Element 3 from rock auto and they are amazing and rust resistant

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.

I'm using a set of Girodiscs all around with the AP Racing calipers and it's a fantastic combo.

I have them on the Brembo front bbk on my e39 N5 and really like them for street use.

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.

I have moved over to power stop as well. I've had problems with the Raybestos E3.
