Girodisc Rear Brake Rotors – Alfa Romeo Quadrifoglio / Maserati
The Girodisc A2-224 Rear Rotor Kit is a high-performance, direct replacement for factory rear rotors on Alfa Romeo Quadrifoglio and select Maserati models. Built to withstand extreme heat and aggressive driving, these lightweight two-piece rotors improve cooling efficiency and responsiveness while maintaining OEM brake balance and ABS function.
Lightweight Performance Meets Italian Engineering
Each rotor is crafted using Girodisc’s precision two-piece floating design—featuring a CNC-machined 6061-T6 aluminum hat paired with a proprietary cast-iron friction ring. The curved vane internal geometry acts as a centrifugal air pump, forcing cool air through the disc to reduce heat, fade, and warping during track or spirited driving. The result: consistent, confidence-inspiring braking performance without compromising everyday drivability.

Girodisc A2-224 Rear Rotors – Alfa Romeo Quadrifoglio / Maserati FAQs
Do these rotors fit the stock calipers? Yes. The Girodisc A2-224 rear rotors bolt directly to the OEM calipers without modification, maintaining proper brake bias and system balance.
What benefits do two-piece rotors offer? They significantly reduce unsprung weight, improve cooling, and allow the rotor to expand under heat without warping or coning, resulting in consistent braking and longer life.
Can I reuse the hats? Yes. When the iron rings wear out, simply replace the rings while reusing the aluminum hats and hardware for a cost-effective rebuild.
Are replacement rings available? Absolutely. Girodisc offers replacement iron rings that fit perfectly onto your existing aluminum hats.
Do these rotors make noise? No. The anti-noise spring washers eliminate rattles when cold while preserving full float during heat cycles.
Are these rotors lighter than OEM? Yes. The aluminum hat reduces rotational mass and unsprung weight, improving responsiveness and handling.
