Design and serviceability
The iron friction ring and aluminum hat separate the rotor’s braking surface from its mounting section. CM-250 iron is heat treated and surface machined, while the aluminum hat provides a lightweight mounting structure. The slotted face helps maintain a clean pad contact surface during braking.
The floating ring-to-hat connection allows thermal expansion as brake temperatures rise. Directional internal vanes guide cooling air through the rotor; install each assembly on its specified side.
Brake-package requirements
Factory M Compound iron brakes; not a direct replacement for carbon-ceramic rotors.
Hat finish and installation
Available hat finish: Mil-Spec Black Hard Coat Anodizing; Mil-Spec Hard Coat Anodizing. Paragon recommends the undyed hard-anodized finish for heavy track use because dyed black hats can discolor under high heat. Choose for your use case, then follow the Paragon general rotor installation and bedding guide (PDF).
What is included
Two assembled rotor units for the listed axle and access to the Paragon general rotor installation and bedding guide (PDF).
Product FAQs
Are these 380x36mm rotors for the front or rear?
This listing is for the front axle and includes two rotor assemblies for BMW G87 M2 / G80 M3 / G82 M4.
Which brake system do they fit?
Factory M Compound iron brakes; not a direct replacement for carbon-ceramic rotors. Match the installed hardware, not just the vehicle model.
Is this a complete brake kit?
No. This listing supplies a rotor pair. Calipers and brake pads are not included.
Which hat finish suits track use?
Paragon recommends undyed hard anodizing for high-heat track use. Dyed black hardcoat hats can discolor at high temperatures; confirm the available finish in the selector.
