Girodisc D1-070 Ferrari 328 GTB/GTS, Mondial Front Replacement Ring FAQs
Can these be used with OEM Ferrari rotor hats? No. These replacement rings are made exclusively for Girodisc aluminum hats and will not fit OEM or aftermarket one-piece rotors.
What pad compounds are recommended? For spirited road use, Ferodo DS2500 or Pagid RS42 pads pair perfectly. For track driving, Pagid RSL29 provide excellent high-temperature control.
Are these rotors directional? Yes. Each rotor is labeled for left and right installation, ensuring proper airflow through the internal curved vanes for optimal cooling.
Do these improve performance over OEM rotors? Absolutely. The two-piece design reduces unsprung weight and improves heat dissipation, leading to stronger, more consistent braking under repeated load.
Enhance your classic Ferrari’s braking system with Girodisc D1-070 300mm front replacement rings — engineered for precision, cooling efficiency, and authentic performance worthy of Maranello’s legacy.
