McLaren 750S/765LT (2017-2026) Girodisc Rear 390mm 2-piece Iron Rotor Conversion

Upgrade the rear braking performance of your McLaren with the Girodisc 390mm Rear 2-Piece Rotor Conversion — engineered as a direct replacement for factory carbon ceramic discs.

Designed for high-performance driving, track use and repeated heat cycles, these rotors provide consistent braking performance and improved cooling over OEM carbon ceramic setups.

This system is ideal for drivers who want predictable braking feel, lower running costs and improved durability under load.

💥 Why You’ll Want This

• 🏁 Consistent rear braking performance under heavy load
• ❄️ Superior cooling with advanced curved vane design
• 🔁 Replaceable rotor rings for long-term cost savings
• ⚖️ Reduced unsprung weight vs traditional one-piece rotors
• 🛠 Direct bolt-on fitment with factory calipers

⚙️ Key Features

• 390mm diameter rear rotor upgrade
• 2-piece fully floating rotor design
• High-carbon cast iron rotor rings
• 6061-T6 aluminium hat (black anodised finish)
• High-strength floating hardware system
• Manufactured in-house by Girodisc (USA)

The internal vane design acts as a centrifugal pump, pulling air through the rotor for improved cooling under hard braking.

🛠️ Performance Benefits

Compared to OEM carbon ceramic brakes:

• Improved heat dissipation during repeated braking
• More consistent pedal feel on track
• Lower long-term replacement costs
• Better suited for aggressive driving and track use

Girodisc rotors are designed to maintain OEM brake balance and system compatibility, meaning no compromise in ABS or stability systems.

🚘 Fitment

✔ Designed for rear axle fitment
✔ Direct replacement for factory carbon ceramic rotors
✔ No modification required when paired with correct pads

📌 Fitment Notes

• 390mm rotors are typically used on higher-performance / track brake packages
• Standard setups may use smaller 380mm rear rotors — confirm before ordering
• Always confirm brake package (standard vs MSO / track) prior to purchase

📦 What’s Included

• Pair of Girodisc 390mm rear 2-piece rotors
• Aluminium hats pre-mounted
• Floating hardware and mounting components

📌 Additional Notes

• Designed as an iron rotor conversion (from carbon ceramic)
