High-performance two-piece floating brake rotors by Girodisc, engineered for the McLaren 600LT, Artura, 720S, and 765LT

Description

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.

Fitment Notes

• 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.

Included

• 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.

Product Specs

• 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.

Product Features

• 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.
