GiroDisc GD355.32.52 replacement rings are a 355 x 32mm service option for the exact brake assemblies listed below, including the rear of the BMW M2 CS Racing Clubsport 450 PS. Diameter alone is not sufficient to establish compatibility with a brake bell or caliper.
The cast-iron rings use a curved internal vane design. Their mounting dimensions must match the original centre bells for the specified application, including the annulus, mounting holes and air gap. This part number is also the listed service ring for the GiroDisc A2-296 assembly.
Key Features
- 355 x 32mm replacement iron rings
- 52mm annulus with 10 mounting holes
- 16mm air gap
- Supplied as a pair of rings with two hardware kits
