I was more than happy with my R1 Rotors at Sonoma 2 weeks ago. I felt a bit of pulsing when I got the brakes especially hot, but I never had any real fading.
Replaced with girodisc two piece rotors. They are great!
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.
Installed new r1 concepts drilled and slotted rotors. After break-in, I noticed a clicking sound from both front rotors, resembling a wheel of fortune. The sound happens when a pad is in. The r1 concepts rotors are dimple instead of drilled all the way through, unlike my previous Power Stop rotors. Brakes feel great otherwise, but this pesky clicking noise when I have windows down will drive me nuts. I may go back to Power Stop.
I personally have had a bad experience with r1 brakes two different times on two different cars. Not saying they're bad just won't buy again. Rotors warped almost immediately both times. New pads and rotors on both cars.
