Construction

Rotor Rings

Cast from Paragon’s CM-250 high-carbon alloy, the rings are heat-treated for stress relief and CBN-machined for a perfectly flat surface. This ensures improved pad bedding, better bite, and reduced risk of cracking during aggressive use.

Aluminium Hats

Manufactured from aerospace-grade 6061-T6 aluminium, the hats are CNC-machined and MIL-A-8625 Type III hard anodised for corrosion and heat resistance. An integrated iron sleeve supports OEM e-brake function while keeping weight down.

Finish Options

• Clear Hard Anodised: Won’t discolour under track heat – ideal for motorsport use
• Black Dyed Hardcoat: May discolour above 260°C (500°F) – ideal for street/mixed use

Compatibility

• BMW M2 F87 – Rear (with Blue M Compound Calipers)
• BMW M3 F80 – Rear (with Blue M Compound Calipers)
• BMW M4 F82 / F83 – Rear (with Blue M Compound Calipers)
