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 Design: Aluminum hats and high-carbon steel rotors reduce pair weight to 8.7 lbs from OEM 12.5 lbs, improving acceleration, braking, and suspension response.
- High-Carbon 72 Alloy: Resists thermal cracking and warping under high loads, maintaining flatness for consistent pedal feel.
- Hard Anodized Hats: 6061-T6 aluminum with stainless steel bimetallic wear indicators lasts longer than cast iron hats.
- High-carbon 72 steel rotors measure 278mm diameter x 22mm thick with slotted faces and curved vanes for cooling.
- Slotted Rotor Faces: Narrow slots enhance initial bite, expel brake gases and dust, and increase pad life during aggressive driving.
- Curved Internal Vanes: Direct cooling air to rotor faces for 20% better heat management over solid rotors, preventing fade in repeated hard stops.

Frequently Asked Questions
Will this fit my 2008-2015 Mitsubishi Lancer?
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 ...
