Construction
Rotor Rings
Cast from Paragon’s proprietary CM-250 high-carbon alloy, the rings are heat-treated to release stress and prevent cracking. Each is finished with CBN precision machining to maintain flatness and support clean pad contact under high load.
Aluminium Hats
Manufactured from aerospace-grade 6061-T6 aluminium, the rotor hats are CNC-machined and MIL-A-8625 Type III hard anodised for corrosion and wear resistance. Excess material is removed to save weight while preserving rigidity under track conditions.
Finish Options
- Clear Hard Anodised: Resists discolouration under high heat – ideal for track use
- Black Dyed Hardcoat: May discolour above 260°C – best for street or mixed use
Compatibility
- BMW F90 M5 – Rear
- BMW M8 F91 / F92 / F93 – Rear
Fitment Notes
- Direct bolt-on fitment – no modifications needed
- Maintains OEM ABS, brake bias, and electronic systems
- Works with OEM or aftermarket pads of matching depth (D)
