Alfa Romeo Giulia / Stelvio Quadrifoglio Front Iron Rotor Conversion
Transform your Alfa Romeo Giulia or Stelvio Quadrifoglio’s braking performance with Girodisc’s front iron rotor conversion kit. Designed as a direct replacement for the OEM carbon-ceramic discs, this setup delivers improved thermal stability, serviceability, and cost efficiency without compromising stopping power. The result is a lighter, cooler, and more consistent braking system perfectly suited for both spirited street driving and track use.
Smart Engineering for Real-World Performance
While the factory carbon-ceramic rotors perform admirably, they’re costly to maintain and can struggle with temperature management during extended sessions. Girodisc’s cast-iron conversion addresses those issues with a more practical, high-performance solution. These rotors feature a reduced 66 mm annulus to keep weight low while retaining full pad contact. Each unit is built from Girodisc’s proprietary high-carbon alloy and uses a 12-pin floating mount system to handle heat expansion smoothly. The directional curved vane design pumps cooling air through the rotor for exceptional heat dissipation.

FAQs –Girodisc A1-209 Alfa Romeo Quadrifoglio Iron Rotor Conversion
Why switch from carbon-ceramic to iron rotors? Iron rotors handle heat cycling better for repeated track sessions and are more affordable to maintain.
Do I need different brake pads? Yes. A pad with a 66 mm or smaller annulus must be used for proper fitment and balance.
Will these fit directly to my OEM calipers? Yes, the rotors are designed to bolt directly to the stock Brembo 6-piston calipers.
Are these rotors noisy? No. Girodisc’s anti-noise spring washers prevent the rattles often associated with floating rotors.
Upgrade your Quadrifoglio’s stopping performance with Girodisc’s front iron rotor conversion. Enjoy improved cooling, predictable pedal feel, and race-ready consistency—without the high cost of carbon-ceramic replacements.
