Brake discs GiroDisc or OEM BMW

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.

Have girodisks on my turbo 987.1 s, love them. Much better feel and braking performance

Yup. Love them on my 987.1.

I have girodisc’s on my 981 cayman, they are fantastic rotors, I started off with DS2500 pads but I used up >50% of all the pads in one track weekend at road Atlanta, I’ve got another event this weekend but I’m running DS1.11 this time around.

I’m seeing some very small cracks on the cross-drilled holes. At what point does this become concerning? These are the front rotors on a new G82 M4 comp after about 6 track days using Pagid R29 Yellow pads which I’ve used before with no issues. My preference is to keep the stock rotors rather than switching to non cross drilled rotors

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.

If that's a factory BMW floating rotor keep a very close eye on that. Have seen more than one of those come apart (crack gets to edge, ring breaks away from hat), locks a wheel and full sends you in that direction towards the barriers.... Good buddy totaled his z4m and did like 6-7k of armco damage when that happened

You need the Msport brakes unless you want new rotors every 5,000 miles. Have a 540i that didn’t come with them and was a nightmare until I upgraded.
