Alfa Romeo Giulia / Stelvio Quadrifoglio 350mm Rear Iron Conversion Brake Discs for track-focused road cars. Two-piece floating brake disc construction helps manage heat, reduce fade, and improve braking consistency under repeated hard use.
Made to order. Production and dispatch usually take about 30 days from order confirmation.
Brake disc measurement: 350mm rear, an iron-rotor conversion sized for Giulia and Stelvio Quadrifoglio cars fitted from factory with carbon-ceramic rear discs.
Two-piece floating construction: an aluminium bell decoupled from a high-carbon cast iron friction ring, cutting unsprung weight and letting the disc expand under heat without warping.
As an iron conversion, this disc requires the corresponding conversion caliper bracket to replace the factory carbon-ceramic setup — please confirm your current brake configuration before ordering.
Suitable for road, fast-road, and track-day use when paired with the correct pads and fluid.
Fits Alfa Romeo Giulia and Stelvio Quadrifoglio originally fitted with the factory carbon-ceramic rear brake option, converting to an iron rotor setup. Always confirm your exact caliper part number, current brake type, and disc bell diameter before ordering, since this is a conversion kit and fitment errors are costly.
