Girodisc Rear Brake Rotors – Ferrari F40

The Girodisc A2-221 Rear Rotor Kit is a precision-engineered, direct replacement for the factory rear rotors on the legendary Ferrari F40. Designed to deliver superior heat management, reduced unsprung mass, and uncompromised performance, these lightweight two-piece rotors bring modern racing technology to one of the most iconic supercars ever built.
Modern Engineering for a Legendary Supercar
Each Girodisc A2-221 rotor combines a CNC-machined 6061-T6 aluminum hat with Girodisc’s proprietary cast-iron friction ring. The floating two-piece design allows the iron ring to expand under heat without warping or coning, maintaining consistent pedal feel and reducing stress on the braking system. The curved-vane internal geometry acts as a centrifugal air pump, improving airflow through the rotor for cooler, more stable braking under extreme conditions.

Girodisc A2-221 Rear Rotors – Ferrari F40 FAQs
Do these rotors fit directly without modification? Yes. The Girodisc A2-221 rotors bolt directly to the factory calipers and hubs without requiring any changes to your OEM components.
What makes these rotors better than stock? The two-piece floating design reduces weight, improves cooling, and prevents distortion under high temperatures for more consistent braking and longer life.
Are replacement rings available? Yes. Girodisc offers replacement cast-iron rings so you can reuse your existing aluminum hats and hardware, reducing long-term maintenance costs.
Do these rotors make noise? No. Anti-noise spring washers are used to eliminate rattling at low speeds while maintaining full float during heat expansion.
Are they sold individually or as a set? The Girodisc A2-221 rear rotors are sold as a matched pair for the rear axle.
Will they affect braking balance or ABS? No. These rotors maintain the factory bias and ABS function while offering improved performance and reliability.
