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 Modular Design: Forged 6061-T6 aluminum hats separate from rotor rings for simple servicing and lower replacement costs over time.
  • Weight Reduction: Each rotor weighs 19.6 lbs versus stock 28.4 lbs for 38% savings per side improving suspension feel and acceleration.
  • Lug Compatibility: Hats drilled to accept both M12 and M14 lugs for precise fit across GT-R variants with stainless steel floating hardware included.
  • DBA Slotted Surface: Precision slots clear gases and debris while channeling heat away to maintain pad contact and prevent fade during hard stops.
  • Curved Internal Vanes: Direct cooling air through the rotor vanes boosting heat dissipation by up to 20% over solid discs.
  • Bolt-on fit using OEM calipers no modifications required.

Frequently Asked Questions

Will this fit my 2012-2024 Nissan GT-R?
That year, make, and model range is listed, but the exact trim, axle position, rotor dimensions, caliper, brake package, and every application note must also match.

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 ...
