These GiroDisc replacement rotor rings service the exact hat, diameter, thickness, annulus, and mounting interface identified below. Similar-looking rings are not interchangeable, so every dimension and the required hat system must be confirmed before ordering.
Key Features
- 2-Piece Floating Design: 6061-T6 aluminum hat expands independently from the high-carbon steel ring to prevent warping under extreme heat.
- Weight Reduction: 26.5 lbs per rotor versus OEM 34 lbs cuts rotational mass for quicker acceleration and suspension response.
- Curved Vane Cooling: Internal vanes direct air through the rotor boosting thermal capacity by 20 percent over stock.
- Stainless Steel Bobbin Hardware: Floating pins allow thermal growth while maintaining precise rotor-to-hat alignment.
- Slotted Rotor Face: Channels brake dust and gases away from pads for consistent bite in wet or dry conditions and extends pad life.
- Retains OEM hub-centric fit with 84mm center bore.

Frequently Asked Questions
Will this fit my 2015-2019 Chevrolet Corvette?
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.
Will these rings fit factory or another brand',s hats?
Do not assume so. Most GiroDisc replacement rings are designed only for the specified GiroDisc hats unless the listing explicitly identifies a factory, Brembo, StopTech, or PFC interface.
Should the old mounting hardware be reused?
Use only the hardware method GiroDisc specifies for this exact ring. Some kits include new hardware, while factory-hat applications may require reuse or separately sourced hardware.
Installation Instructions
Replacement-ring service involves safety-critical brake hardware. Follow the current GiroDisc assembly instructions, confirm the exact hat interface and ring direction, use only approved hardware, torque fasteners in the required sequence, check runout and clearance, and complete the specified bedding process.
