The GiroDisc system provides a hassle-free solution as a direct replacement for the factory disc. Customers can install the GiroDisc system without any modifications, as it bolts directly to the car and seamlessly integrates with OE calipers. By opting for these lightweight high-performance replacements instead of a big brake kit, drivers can maintain their factory bias and ABS efficiency.

The central hat section of the rotor is meticulously crafted using 6061-T6 aircraft specification aluminum sourced exclusively from the United States. Our proprietary cast iron, poured and machined in-house at GiroDisc, forms the disc itself. To ensure efficient cooling, the rotor features 48 curved directional vanes, derived from racing technology, acting as a centrifugal pump that effectively directs cooling air through the disc.

For secure and reliable performance, the rotor and hat utilize a floating mount system. This system incorporates 10 high-strength alloy steel drive pins, manufactured to our precise specifications by GiroDisc in the USA and treated with cadmium plating to enhance corrosion resistance. These pins bear the braking load while maintaining the necessary axial and radial float between the hat and disc. Class 12.9 cap screws, along with hardened washers, secure the pins in place. To prevent noise during cold starts, anti-noise spring washers are mounted on the rotor side of the pins, allowing for expansion with heat while eliminating unwanted rattling commonly associated with floating rotors. Moreover, this floating design facilitates self-centering between the pads, ensuring optimal performance.

With the GiroDisc system in place, customers can simply replace the cast iron rotor as needed, making maintenance straightforward and efficient.

Please note that the GiroDisc system is sold and priced per pair for your convenience.

Introducing GiroDisc 2-Piece Rotors, a direct replacement option for the E46 M3 345mm rotor found on Competition Package (ZCP) and CSL models. These rotors, weighing 17.5 lbs per rotor assembly, offer a substantial reduction in weight compared to the factory rotors at 19 lbs per rotor. By incorporating fully floating assemblies, these rotors effectively reduce unsprung weight and rotating mass from the front axle of the vehicle.

Crafted from GiroDisc's proprietary casting, the rotor rings are machined from high-carbon steel formulated to their exact specifications. This exceptional metallurgy ensures durability and longevity, while the 48 curved vanes serve as a centrifugal pump, efficiently drawing air in through the hub for optimal cooling during intense usage. With a 2-piece design, the hat is reusable and can be easily attached to new rings (part number D1-012) when replacement becomes necessary.

All key components, including the hats, rotor rings, and drive pins, are meticulously manufactured in-house at GiroDisc's facility located in Bellingham, WA, using domestically sourced materials. The hat, constructed from 6061-T6 aluminum, features a sleek black anodized finish, while the drive pins are composed of a high-strength steel alloy and cadmium-plated for superior corrosion resistance. Each rotor is meticulously assembled using spring clips and Belleville washers, providing a race-ready float without any loose hardware-induced noise, ensuring a street-friendly experience as well.

Not only are these E46 M3 rotors compatible with stock sliding calipers found on ZCP and CSL cars, but they have also been designed with common aftermarket caliper setups in mind. This includes the Brembo calipers from both the Porsche 996 and Megane RS swaps, providing versatility and flexibility to meet various performance needs.

Key Specifications:

Diameter: 345mm
Thickness: 28mm
Weight: 17.5 lbs per rotor assembly

It is recommended to replace the rotor rings when they reach a minimum thickness of 26mm or if a crack extends to the edge of the ring. Trust GiroDisc to deliver exceptional quality and performance for your braking needs.
