The Girodisc 2‑Piece Front Rotors for 720S / 600LT replace the heavy, restrictive stock carbon‑ceramic or OEM rotors with a race‑inspired, two‑piece iron‑and‑aluminum rotor system that dramatically improves brake performance, cooling, and consistency. With lighter unsprung and rotating mass plus superior heat dissipation, these rotors deliver stronger, more confident braking — whether you’re carving twisties, commuting, or pushing hard on the track. They bolt directly onto factory hubs and calipers, offering a direct‑fit, performance‑upgrade path for drivers who demand repeatable, predictable braking under real conditions.
Compatible with McLaren Artura / 600LT / 720S / 765LT when equipped with the stock front‑brake setup (390 mm front brake configuration).
Direct‑bolt replacement — installs on factory hubs and works with OEM calipers and mounting hardware (no modification required).
Uses a smaller pad‑swept annulus (66mm or less) than OEM carbon‑ceramic rotors — users must ensure brake pads with appropriate pad shape (e.g., FMSI‑standard D1405) are used to maintain pad‑to‑rotor contact area.
Pair of 2‑piece front rotors (left and right), consisting of a 6061‑T6 aluminum “hat” and high‑carbon cast‑iron rotor rings.
All necessary floating‑mount hardware: high‑strength alloy steel drive pins (cadmium‑plated), cap screws, hardened washers, and anti‑noise spring washers to prevent rattles when cold but allow thermal expansion.
Rotor design: Two‑piece floating rotor (aluminum hat + cast‑iron disc ring) engineered for high performance and durability.
Cooling: 48 curved internal vanes forming a centrifugal‑pump design that draws air through the disc — improving cooling under repeated heavy braking and reducing fade under heat.
Material: Cast‑iron friction ring (USA‑made, high‑carbon iron) + 6061‑T6 aluminum hat (hard‑anodized finish) for lightweight strength and thermal stability.
Weight/Unsprung mass: Significantly reduced compared to OEM CCM (carbon ceramic) rotors — lighter rotating and unsprung mass improves suspension & brake response.
Serviceability: Rotors are rebuildable — when the iron ring wears/warps, you replace only the disc ring, not the entire rotor assembly.
Superior heat dissipation & fade resistance — The curved‑vane, ventilated design actively pumps air through the rotor under braking, keeping rotor temperatures lower lap after lap for consistent pedal feel and braking performance.
Reduced unsprung & rotational mass — Two‑piece construction lowers the mass the suspension and brakes must control, improving suspension responsiveness, throttle/brake modulation, and overall handling feel.
Direct replacement, no modifications — Bolts onto factory hubs and uses OEM calipers and mounting points — makes installation straightforward for shops or experienced garages.
Rebuildable for cost‑effective maintenance — Only the cast‑iron rotor rings wear — hat assemblies can be reused indefinitely, reducing long‑term replacement cost compared to one‑piece rotors.
Improved pedal feel & braking modulation — Floating rotor hat design and consistent ring material give predictable, smooth brake feel under both street and track use, avoiding the “grabby” or variable nature of some carbon‑ceramic rotors.
Track‑ready yet street‑friendly — Engineered for repeated heavy braking on track without sacrificing everyday usability — compatible with OEM ABS and brake electronics, and works with standard or high‑performance brake pads.
