The GiroDisc slotted rear ring for 2020 Subaru WRX with Brembo calipers and Performance Package is a direct-fit rear-ring replacement. Its slotted face helps clear pad-surface gases and debris to support consistent contact. Supplied for WRX rear brake assemblies that use Brembo calipers in the Performance Package, the ring mounts to the appropriate center hat for those rear applications.
