Girodisc Rear 2 Piece Rotors for McLaren 12C 2012-2014 - Cast Iron & Aluminum Design - A2-023

Girodisc A2-023 Rear 2 Piece Rotors for McLaren 12C (2012-2014)

The Girodisc A2-023 rear rotors are engineered as a direct replacement for the factory cast iron rotors found on the McLaren 12C models from 2012 to 2014. These rotors deliver enhanced performance and durability, making them an ideal upgrade for those seeking improved braking efficiency.

Construction and Design

The A2-023 features a unique construction with a central hat made from 6061-T6 aircraft-grade aluminum, ensuring a lightweight yet robust foundation. The rotor itself is crafted from high-quality cast iron, adhering to the same specifications utilized by professional racing teams. This combination not only reduces weight but also enhances thermal performance.

Cooling Technology

Incorporating a curved vane design, these rotors function effectively as a centrifugal pump, channeling cooling air through the disc. This design significantly reduces the risk of brake fade during high-performance driving conditions, providing consistent stopping power.

Floating Mount System

The Girodisc A2-023 utilizes a floating mount system that incorporates ten high-strength alloy steel drive pins. These pins are manufactured to Girodisc's specifications and are cadmium plated to ensure long-lasting corrosion resistance. This system allows for axial and radial float between the rotor and hat, accommodating thermal expansion while preventing noise from cold braking.

Installation and Maintenance

Installation is straightforward; once the Girodisc system is mounted, future maintenance is as simple as replacing the rotors when necessary. When paired with performance brake pads and high-temperature brake fluid, the A2-023 rotors provide a reliable solution to issues such as overheating and warping, common in high-performance applications.

These rotors are sold in pairs, making it easy to upgrade your braking system for enhanced performance on the track or the road.
