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. Key Features • Direct replacement for factory rotors – no modification required • Requires use of 66mm annulus pads (FMSI 1382/1405) • Fully floating design for thermal compensation • Made in the USA from premium materials • Sold/priced per pair 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.

For Drivers Who Demand the Utmost From Their Car Designed and tested specifically for track-day enthusiasts and drivers who demand the utmost performance from their cars, these kits offer superlative performance for both everyday driving and demanding track-day sessions. Brembo kits consist of cross-drilled or slotted, ventilated two-piece discs and aluminum calipers with six pistons; a complete set of high performance pads; metal-braided hoses; and high quality hardware. Solutions and Technologies Born on the Race Track Braking systems consisting of motorsports-derived components offering levels of technology and performance without par on the market today and embodying the purest expression of Brembo's state-of-the-art technology. The kit consists of aluminum calipers with opposed pistons which, depending on the car model and in increasing order of performance, may be composite, monoblock or even billet monoblock components, combined with cross-drilled or slotted one-piece or composite oversized discs. Brembo kits combine the best solutions available to offer the perfect solution for the individual characteristics of each model. The heart of the kit consists of aluminum calipers. These are also available as monoblock parts machined from a single billet of cast aluminum, which ensure outstanding rigidity and minimized deformation. The discs supplied in the kit, which may either be floating or one-piece, depending on the specific car model, feature an exclusive venting system that improves cooling capacity and increases resistance to cracking caused by thermal shock by over 40%. Cross-drilled and slotted finishes are designed and executed with meticulous precision. These holes or slots in the braking surface help dissipate heat and eliminate brake dust and gases. A set of high-performance brake pads with specific friction materials for each application, TÜV/DOT homologated metal-braided hoses, an adapter and high-quality fastener hardware complete the kit. More Braking Torque and Thermal Capacity on Track Using radial-mounted fixed calipers together with oversized discs gives the system greater braking torque and superior thermal capacity. The result is a braking action that is noticeably more immediate and decisive even in normal road usage, and is extraordinarily powerful and consistent under the repeated loads of track use. Fixed calipers improve the durability and efficiency of the system: the opposed multiple pistons act on the pads with more precision, due to the smaller piston diameter and the reduced pressure exerted on each individual piston, while the greater overall surface area between the pads and pistons results in more uniform friction surface wear. The superlative stiffness of the calipers and the metal braided hoses reduce brake fluid absorption. The result is improved, more stable brake pedal pressure, making it possible to modulate braking force more precisely and enhancing pedal feel. Featuring a hat in aluminum alloy, the oversized floating disc system reduces unsprung mass (for improved handling) and thermal stress. The mounting system is engineered to permit a greater degree of both radial and axial float. This characteristic, together with the greater dimensions of the braking rotor surface, improves the dispersion of the heat generated by the repeated, intense thermal stress that the discs are subjected to, for consistent braking performance and pedal feel even after numerous laps on the track. Eye-Catching Colors and Unique Looks With a combination of painted calipers (available in red, yellow, black or silver) flaunting the Brembo logo, and slotted or cross-drilled discs, the Gran Turismo kit gives an unmistakably sporty, eye-catching look to the car, offering that extra special touch for drivers who want their vehicle to stand out from the crowd. Catering to the more discerning driver is the GT-R line of kits. These offer even more performance and consist of billet-monoblock calipers, slotted discs in diameters up to 405 mm and special high performance pads. Brembo Big Brake Kit Details: Caliper Body: Two-Piece Radial Mount Caliper Colors: Black or Red Number of Pistons: 4 Disc Size: 320mm x 28mm Disc Construction: Machined cast iron Disc Type: Drilled Disc Vane Design: Vented straight vane Disc Material: Cast iron, single-piece rotor & hat Front or Rear System: FRONT Goodridge stainless steel brake lines Brembo high-performance brake pads

Do I need to modify anything for installation? No modifications are required. The Girodisc rotors bolt directly to your existing hubs and calipers, maintaining all factory geometry and electronics. How do these compare in weight to PCCBs? They are slightly heavier, but the difference is offset by improved cooling, reduced fade, and greater brake pad compatibility — critical benefits for extended track sessions. Can I reuse the aluminum hats? Absolutely. When the rotors wear out, simply install new Girodisc iron rings onto your existing hats, making replacements quick and economical.
