Not every brake upgrade requires replacing the entire braking system.

In many cases, the factory calipers are already highly capable.

The limiting factor is often the rotor itself.

GiroDisc was founded in 2003 with the goal of improving brake performance through lightweight, two-piece rotor technology. Instead of developing complete big brake kits, the company focuses on direct-replacement rotors that reduce unsprung weight, improve cooling efficiency, and retain factory brake balance while fitting OEM calipers. Designed, engineered, and manufactured in Bellingham, Washington, GiroDisc products have become a popular choice for both street-driven performance cars and dedicated track vehicles.

Improving the Parts That Matter Most

A brake rotor does much more than provide a friction surface.

It must absorb heat, dissipate temperature, maintain dimensional stability, and withstand repeated heavy braking.

GiroDisc addresses these demands through a two-piece floating design that combines a lightweight 6061-T6 aluminum hat with a proprietary high-carbon cast iron rotor ring. Curved internal vanes act as centrifugal pumps, drawing cooling air through the rotor to improve heat dissipation during demanding driving conditions.

Product Categories

GiroDisc offers a comprehensive lineup of braking components, including:

• Two-piece front brake rotors
• Two-piece rear brake rotors
• Replacement rotor rings
• Performance brake pads
• Titanium pad shields
• Caliper rebuild components
• Brake hardware
• Brake service tools

Because the aluminum hat is reusable, many applications only require replacing the rotor ring once it reaches its service limit, helping reduce long-term operating costs.

The product lineup continues expanding as new performance platforms enter the market.

Performance Without Changing Brake Balance

One of GiroDisc's defining advantages is its direct-replacement philosophy.

Rather than requiring different calipers or significant modifications, GiroDisc rotors are engineered to work with the factory braking system. This preserves the original brake bias and ABS calibration while reducing rotational mass and improving thermal capacity. For enthusiasts who want greater braking performance without installing a complete big brake kit, this approach offers an effective solution that integrates seamlessly with the vehicle.

Manufactured Entirely In-House

GiroDisc maintains control over the entire manufacturing process.

Rotor hats, rings, and drive pins are produced in-house using domestically sourced materials, allowing the company to maintain strict quality standards throughout design, machining, assembly, and inspection. This vertically integrated approach has helped establish GiroDisc as a respected name among performance enthusiasts and motorsport competitors worldwide.
