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: Aluminum hats and modular rotor rings allow easy replacement of wear surfaces while keeping total assembly weight low at 19.7 lbs per rotor versus OEM 28 lbs.
  • High Carbon 72 Series Iron: Cast iron rings resist warping and cracking with curved vane internal cooling that pulls heat away faster than solid rotors.
  • Weight Savings: Pair weighs 39.4 lbs reducing rotational mass for sharper turn-in quicker acceleration and less suspension stress.
  • OEM Bolt Pattern: 5x130mm PCD with 72.6mm center bore fits factory calipers and hubs without adapters or modifications.
  • Pair ships fully assembled ready for direct bolt-on installation.
  • No these 350mm rotors fit base Carrera C4 and T models with factory 350mm brakes. Carrera S uses 380mm rotors select A1-211 instead.

Frequently Asked Questions

Will this fit my 2017-2026 Porsche 718 Boxster?
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.

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 ...
