Why choose Girodisc rear 380mm 2-piece rotors
- 2-piece floating construction with a lightweight 6061-T6 aluminium hat and cast iron rotor ring for precise control as temperatures rise.
- Curved vane venting acts as a centrifugal pump to draw cooling air through the disc, helping manage heat and reduce fade.
- Slotted and zinc-coated rotor faces for consistent pad refresh and corrosion resistance.
- Floating mount system with 12 high-strength alloy steel drive pins, cadmium plated for long-lasting corrosion protection.
- Class 12.9 cap screws with hardened washers and anti-noise spring washers to allow thermal growth while keeping things quiet when cold.
- Axial and radial float allows the rotor to self-centre between the pads for smooth, consistent braking.
- Serviceable design - when worn, simply replace the cast iron rotor rings and keep the hats.
- Sold and priced as a pair for the rear axle.
