A1-023 Girodisc 2pc Brake Rotors | McLaren MP4-12C (Front)
$2,136.00
McLaren 380mm Front Rotors, incl. spacers
Unlock consistent, repeatable stopping power with Girodisc two-piece floating front rotors for McLaren models originally equipped with 370mm cast-iron front discs. This upgrade increases diameter to 380mm and includes the required caliper spacers for a true bolt-on installation. You keep factory brake bias and ABS while gaining cooling capacity, lighter rotating mass, and sharper pedal feel.
Race-Bred, Street-Refined
Each rotor pairs a U.S.-sourced 6061-T6 aluminum hat with Girodisc’s proprietary high-carbon cast-iron ring. Curved internal vanes act like a centrifugal pump to move cooling air through the disc under hard use. The fully floating mount system controls thermal growth, helping the rotor self-center between pads and maintain quiet street manners via anti-noise spring/Belleville washers.
Features
Diameter upgrade: 370mm → 380mm for more torque leverage and thermal headroom
Direct fit: Includes caliper spacers; uses factory calipers and pad shape
Two-piece floating design: Reduces unsprung/rotational mass and improves consistency
Curved directional vanes: Efficient internal airflow for superior heat management
Serviceable: Replace rings later and reuse the hats to lower long-term cost
Premium hardware: 12 cadmium-plated alloy steel drive pins with class 12.9 cap screws and hardened washers
Made in the USA: Hats and rings machined in-house for precise fit

Competition Motorsport is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most products the same or next business day to ensure we meet your delivery deadline.
This Girodisc system upgrades your Porsche 981 or 991 equipped with factory PCCB brakes to a 350mm two-piece steel disc and aluminum hat. This two-piece floating rotor design will bolt directly to your Porsche front and work flawlessly with the OEM calipers.
Upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Girodisc rotors maintain the low rotational and unsprung mass of your PCCB rotors while being far more durable -- particularly when swapping wheels on and off at the race track.
Combined with Pagid or PFC performance brake pads and Competition Motorsport RF-1 racing brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked, warped rotors that result from high-performance driving.
The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc.
The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion. Anti-noise spring washers eliminate the noise typically associated with floating rotors.
This two-piece Girodisc design allows for disc-only replacement, reusing the hat to minimize maintenance costs.

Are these rotors compatible with factory center-lock hubs? Yes. If your Porsche uses OEM center-lock wheels, select the center-lock drive pin option during purchase.
Do these improve braking performance? Yes. The floating design and advanced metallurgy offer better heat control and fade resistance than standard rotors.
Can I use stock brake pads? Yes, factory pad fitment is retained, but upgraded compounds are recommended for track use.
Do these rotors require maintenance? Only normal inspection for wear; replacement rings are available separately to reuse your existing hats.
