The GiroDisc slotted rear ring for 2012–2019 Ford Focus RS Mk III installs as a slotted friction face on the rear rotor to help maintain pad contact and evacuate gases and debris during aggressive driving. Supplied as rear direct-fit rings for Focus RS applications, they replace the rotor friction surface—check pad compatibility and installation requirements before fitting.
