Product Description

The GiroDisc rotors for 981 GT4 / Boxster Spyder convert your brake system from expensive  OEM rotors to a high-performance, track-ready set of iron rotors with improved cooling, strength, and consistency. These two-piece floating rotors feature a lightweight aluminum hat and cast-iron braking surface engineered to deliver stronger stopping power under heavy use, reduced unsprung weight for improved suspension response, and enhanced heat dissipation to resist fade — ideal for spirited driving or track days without sacrificing daily drivability.

Fitment Notes

  • Engineered to fit Porsche 997.1 Turbo (OEM PCCB), 981 Cayman GT4 & 981 Boxster Spyder (OEM Iron Rotors) — acts as a direct replacement for OEM rotors.

  • Bolts directly to OEM hubs and works with factory calipers — no custom fabrication or caliper replacement required. 

  • Intended for street, track, or mixed-use — gives reliability and performance whether you’re pushing the car hard or using it daily.

Included

  • Two (2) two-piece floating rotors — each with a cast-iron braking surface and 6061-T6 aluminum “hat.” 

  • Floating-mount hardware including alloy drive pins and special anti-noise spring washers (to allow thermal expansion without rotor “rattle”).

  • Installation kit to reuse OEM calipers, pads, and hubs — rotor swap is bolt-on and uses factory mounting points.

Product Specs

  • Rotor structure: Two-piece rotor (cast-iron disc + aluminum hat) for optimized strength, durability, and weight savings.

  • Cooling design: Curved-vane internal ventilation that acts like a centrifugal pump to draw cooling air through the disc — improves heat rejection and reduces fade during extended heavy braking.

  • Floating mount system: Allows the disc to expand/contract independently from the hat under heat — maintains pad centering, reduces stress on caliper hardware, and improves rotor longevity.

  • Weight & unsprung-mass benefit: Lighter hat + optimized design reduces rotational and unsprung mass compared to stock rotor setups, improving suspension response and handling dynamics.

Product Features

  • Superior Brake Performance & Cooling — The ventilated, floating design with curved-vane cooling dramatically improves heat dissipation and reduces brake fade under heavy loads or track use.

  • Reduced Unsprung & Rotational Weight — Aluminum hat and two-piece design cut mass, enhancing suspension feedback, responsiveness, and overall vehicle agility.

  • Direct OEM-Fitment & Caliper Compatibility — Installs using factory hubs, calipers and brake lines — no additional parts or modifications required.

  • Floating Rotor Design — Allows thermal expansion, self-centering, and improved rotor longevity while maintaining firm brake pedal feel.

  • Cost-Effective Alternative  — Offers performance and durability of OEM brakes but at a fraction of the replacement cost — ideal for track days or aggressive driving.

  • Long Service Life & Racetrack Proven — Built with high-quality materials and engineering, designed to take repeated laps, hard braking, and temperature swings with consistency and durability.
