Transform the braking performance of your Giulia or Stelvio Quadrifoglio with Girodisc’s lightweight two-piece rear iron rotor conversion. Designed to replace the factory carbon-ceramic system, this setup maintains OEM fitment while offering better serviceability and cost efficiency—perfect for high-performance street and track driving.
Direct Bolt-On Iron Rotor Replacement
The Girodisc system is a direct replacement for the original carbon-ceramic rear rotors, requiring no modifications or special adapters. The central hat is precision-machined from U.S.-sourced 6061-T6 aluminum, while the iron rotor rings are Girodisc’s proprietary cast iron, poured and machined entirely in the USA. The curved vane internal design actively pumps cooling air through the disc, reducing fade and improving heat dissipation under heavy use.
