Girodisc D1-110 Ferrari 430 Scuderia Front Replacement Ring FAQs
Do these rotors replace the OEM Ferrari carbon-ceramic discs? No. The D1-110 rings are designed for Girodisc iron rotor conversion kits and will not mount to factory CCM hardware.
What pad compounds work best with these rotors? For mixed road and track use, Pagid RS29 or Ferodo DS1.11 pads perform exceptionally. For racing, use Pagid RSL1 or Endless ME20 compounds for superior high-temp stability.
Are these rotors directional? Yes. Each rotor is marked for left and right installation. The curved internal vanes must face the correct direction for proper airflow and cooling efficiency.
What torque specification should be used for the hardware? Tighten all bolts to 12 ft-lbs (16 Nm) using blue Loctite. After the first heat cycle, verify hardware torque to ensure proper floating action.
