Ferrari 599 GTB Front Iron Rotor Conversion
The Girodisc front iron rotor conversion for the Ferrari 599 GTB delivers a precision-engineered, lightweight solution for upgrading from OEM carbon-ceramic rotors. Designed for exceptional heat management and long-term serviceability, this two-piece floating system bolts directly to factory calipers with no modifications needed.
Lightweight, Track-Ready Performance
Each rotor hat is CNC-machined from U.S.-sourced 6061-T6 aircraft-grade aluminum, paired with Girodisc’s proprietary high-carbon cast iron rotor rings. The curved-vane design acts as a centrifugal pump, forcing cooling air through the discs to reduce fade and extend life under aggressive braking. The assembly is secured using high-strength alloy steel drive pins and anti-noise spring washers for quiet operation and proper thermal expansion.

Ferrari 599 GTB Front Iron Rotor Conversion FAQs:
Does this conversion fit the OEM calipers? Yes, it’s a direct bolt-on solution using the factory Ferrari 599 GTB calipers.
Why do I need different pads? The Girodisc rotors use a shorter annulus area to optimize weight and heat control, so pads with a 66mm swept area are required.
How much weight does this setup save? Compared to OEM carbon-ceramic rotors, the Girodisc conversion saves several pounds per corner, improving response and ride quality.
Is this system rebuildable? Yes. You can replace just the cast iron rings when worn, keeping the aluminum hats for long-term use.
Upgrade your Ferrari 599 GTB with Girodisc’s front iron rotor conversion and experience sharper braking, improved pedal feel, and reduced operating costs over OEM carbon ceramics.
