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 with 4340 steel friction rings float on hard anodized aluminum hardware to expand contract independently preventing hat to ring galling and warping under extreme heat.
- Weight Reduction: Set weighs 43.6 lbs versus OEM 55.6 lbs shedding 12 lbs per side to sharpen steering response accelerate deceleration and boost overall chassis dynamics.
- Direct Fitment: Bolt-on replacement matches OEM pattern 5x120mm hub-centric design no modifications or adapters required.
- Slotted Surface: Curved slots wipe gases clear from pads improve wet performance and pull heat away from friction zone for sustained braking during hard laps.
- Pair includes left and right rotors bed-in with GiroDisc procedure for peak performance.
- High-carbon 4340 alloy withstands track abuse where stock rotors fail.

Frequently Asked Questions
Will this fit my 2015-2021 Honda Civic?
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 ...
