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

These are GiroDisc 380x28mm slotted rotor rings, designed to work with specific Brembo and StopTech big brake kits. They feature 10 pin holes and a 54mm annulus, providing a direct replacement for the rotor rings on those compatible kits. If your big brake kit uses these specific dimensions and mounting patterns, these GiroDisc rings are a well-built option to get your braking system back in top shape.

GiroDisc is known for making solid brake components, and these rotor rings are no exception. They are made from a high-carbon iron alloy, which is a strong material that holds up well to the heat and stress of repeated braking. The slots are machined into the rotor surface to help clear away brake dust and gases that can build up between the pad and the rotor. This slotting helps maintain consistent friction and improves braking performance, especially during repeated hard stops where heat can become a major factor. The 380mm diameter and 28mm thickness are designed to fit within the caliper and hat assemblies of the intended Brembo and StopTech kits, ensuring proper function and fitment.

When replacing rotor rings on a big brake kit, it's important to ensure you have the correct components. These GiroDisc rings are intended as a direct replacement for the rotor rings on specific Brembo and StopTech big brake kits that use a 10-pin mounting system and a 54mm annulus. Always confirm your existing rotor ring dimensions and mounting pattern match these specifications before ordering. Proper installation is crucial for brake system performance and safety; refer to the manufacturer's instructions for your specific big brake kit for guidance on replacing the rotor rings.
