These GiroDisc front replacement rings suit the Renault Megane IV RS. They fit onto existing GiroDisc hats, so the hats are reused and only the rings are renewed when they wear.
Note Unless specifically noted, GiroDisc replacement rings are only designed to work with GiroDisc hats. They are not designed to be used with other brands, including hats from cars equipped with 2-piece rotors from the factory.
