Girodisc D2-209 Alfa Romeo Giulia / Stelvio QV (CCM) Rear Replacement Rotor Rings
The Girodisc D2-209 Rear Replacement Rotor Rings are precision-engineered replacements for Girodisc two-piece rear rotors on Alfa Romeo Giulia and Stelvio Quadrifoglio models equipped with factory Carbon Ceramic (CCM) brakes. These high-performance iron rings convert your carbon ceramic setup to an iron-based Girodisc system, offering superior durability, serviceability, and consistent performance for both street and track use.
Precision Conversion for CCM-Equipped Quadrifoglio Models
Each Girodisc D2-209 ring is machined in the USA from Girodisc’s proprietary cast iron alloy, providing exceptional thermal stability and balanced friction. The internal curved vane design acts as a centrifugal air pump, drawing cooling air through the rotor to prevent fade and maintain braking consistency. Sold as a pair and supplied with new hardware, these rings are a direct bolt-on fit to your existing Girodisc aluminum hats.
