The GiroDisc slotted rear rotor for Porsche 911 GT3 Cup (991) is a rear replacement tailored to that 991 GT3 Cup application. Its slotted face helps channel gases and debris away from the pad contact area to support steadier braking during repeated stops. The rotor is produced for the listed GT3 Cup fitment and serves as a replacement for worn rear rotors in that application.
