GiroDisc 380x28mm 10 Pin Holes 54mm Annulus Slotted Rings for Brembo & StopTech BBKs

GiroDisc replacement cast iron rotor rings, 380x28mm 10 Pin Holes 54mm Annulus Slotted Rings for Brembo & StopTech BBKs. Service rings for an existing two-piece setup: you reuse your aluminum hats and refresh only the friction surface. Match the ring diameter, thickness, pin-hole count and annulus width to the rings currently on the car.
