Frequently Asked Questions
Will this fit my 2023-2026 BMW M2?
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.
