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.

This application uses a fixed-hat, non-floating mounting arrangement. Two-piece construction does not mean every rotor uses a floating connection; match replacement parts and assembly hardware to this specific design.

Brake-package requirements

M Performance / M Sport brake package; verify caliper, rotor size; 160mm parking-brake drum.

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 rotor bedding and installation instructions.

What is included

Two assembled rotor units for the listed axle and installation instructions.

Product FAQs

Are these 345x24mm rotors for the front or rear?

This listing is for the rear axle and includes two rotor assemblies for BMW M Performance / M Sport brake applications.

Which brake system do they fit?

M Performance / M Sport brake package; verify caliper, rotor size; 160mm parking-brake drum. 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?
