BMW M2 F87 M3 F80 M4 F82 Brake Set Discs Pads Calipers

Compatibility: BMW M2 (F87), M3 (F80), and M4 (F82)

Manufacturer: Brembo (Calipers) / BMW M (Rotors)

This complete brake set is the factory-engineered stopping solution for the F-chassis M-power generation. Known for its distinct “M-Blue” finish (standard) or “M-Gold” (Carbon Ceramic), this system is designed to provide consistent deceleration under high thermal loads, making it a popular performance upgrade for standard F30/F32 vehicles as well.

Technical Specifications

• Front Setup: * Calipers: 4-piston fixed aluminum monoblock (Brembo).

  • Rotors: $380\text{mm} \times 30\text{mm}$ cross-drilled, compound (2-piece) ventilated discs.

• Rear Setup:

  • Calipers: 2-piston fixed aluminum monoblock.

  • Rotors: $370\text{mm} \times 24\text{mm}$ cross-drilled, compound ventilated discs.

• Disc Construction: Aluminum hats pinned to cast-iron friction rings to reduce unsprung weight and allow for radial expansion during heat cycles.

Key Performance Features

• Compound Rotor Technology: The 2-piece design significantly reduces the “coning” effect under heat and sheds weight compared to a single-piece cast rotor, improving steering response and suspension compliance.

• Cross-Drilled Surface: Provides a path for gases and water to escape from the friction surface, ensuring a consistent “bite” even in wet conditions or during aggressive track sessions.

• Brake Cooling Air Ducts: The calipers are positioned to work in tandem with the vehicle’s front bumper air ducts, utilizing the venturi effect to pull heat away from the center of the hub.

• High-Friction Pad Compound: Factory pads are optimized for a high initial bite. (Note: These are semi-metallic and may produce “M-Brake Dust” under normal operation).

Professional Installation & Cataloging Notes

When managing these sets for inventory or retrofits, ensure these technical standards are followed:

1. “M Sport” vs. “M Performance” (2NH): In later models (especially the M2 Competition), a larger Silver or Red 6-piston front/4-piston rear set ($400\text{mm}/380\text{mm}$) was introduced. Verify rotor diameter to ensure the correct caliper bracket is used.

2. Coding (DSC Retrofit): If installing this M-brake set on a standard 3 Series (F30) or 4 Series (F32), the vehicle’s DSC (Dynamic Stability Control) module must be coded to the “M-Performance Brake” setting to adjust the brake bias and master cylinder pressure curves.

3. Minimum Wheel Clearance: Due to the $380\text{mm}$ rotor and large 4-piston caliper, a minimum wheel size of 18 inches is required. Note that some 18″ aftermarket wheels with thick barrels may still interfere with the caliper weights.

4. Hardware Replacement: BMW recommends replacing the Caliper Bolts (one-time use stretch bolts) and the Rotor Retaining Screws during every major installation to maintain factory safety torque specs ($30\text{ Nm} + 90\text{°}$)
