This GiroDisc two-piece brake rotor set is engineered for the exact brake configuration shown below. Its reusable aluminum hats and replaceable cast-iron friction rings reduce service waste while preserving the factory caliper relationship when the application notes are followed.

Key Features

  • Two-Piece Construction: 6061-T6 aluminum hats save 25% weight over OEM PCCB rotors (21.5 lbs each vs 28.6 lbs) to improve suspension response.
  • High Carbon Alloy Iron: Resists thermal cracking and warping with friction surfaces slotted on both sides for even wear.
  • Floating Hardware: Stainless steel bobbins allow thermal expansion between hat and ring preventing stress buildup.
  • Slotted Rotor Faces: Channels water gases and pad residue away from the surface for immediate bite in wet dry or high-heat conditions.
  • 72 Curved Vanes: Direct airflow through the rotor core to pull heat away and maintain pad temperatures during repeated hard stops.
  • Bolt-on replacement using OEM caliper hardware and pads.

Frequently Asked Questions

Why does this listing require fitment verification?
GiroDisc identifies the part by a brake-system or race application that cannot be converted safely into a complete year-make-model range without confirming the exact vehicle and brake configuration.

Can I use my factory calipers and brake pads?
Many GiroDisc rotor sets retain the factory calipers, but some iron conversions require a different pad shape or compound. Follow the exact application note for this part number.

Are these rotors sold individually or as a pair?
GiroDisc commonly sells these assemblies as an axle pair, but confirm the quantity shown for this exact part number before ordering.

Installation Instructions

Follow the current GiroDisc instructions and vehicle service information. Confirm the brake package and rotor direction, clean mounting surfaces, inspect hubs and calipers, torque all fasteners to the specified values, verify clearance, and complete the required pad-bedding procedure before normal use.

This collection includes vehicle-specific and motorsport braking components from DBA, EBC Brakes Racing, GiroDisc, Rotora, Wilwood, and other performance brake manufacturers for street-performance, track, racing, and high-output applications. Two-Piece Performance Brake Rotors A two-piece brake rotor separates the iron friction ring from the center hat. The components are connected using application-specific drive pins, bobbins, bolts, or other mounting hardware. Many systems use an aluminum hat to reduce weight and limit heat transfer toward the hub compared with a similarly sized one-piece iron rotor. Construction varies significantly between manufacturers. Some products are fixed two-piece assemblies, while others are fully floating or semi-floating designs that allow controlled movement as the friction ring expands under heat. The terms ...
