BMW F22 F87 M3 F80 M4 F82 Brake Set Discs Pads Calipers

Compatibility: BMW M3 (F80), M4 (F82/F83), M2 (F87) | Retrofit: F20, F22, F30, F32, F36

This brake set is the factory-engineered “M-Sport” braking solution, designed for high-thermal capacity and repeated high-speed deceleration. The system is most recognizable by its Estoril Blue (standard) or Silver/Red/Gold (Performance/CS/CCB) calipers and is a direct bolt-on upgrade for the standard 2, 3, and 4 Series chassis.

Technical Specifications

The standard M-set (Option S2NH) utilizes a staggered piston configuration to provide balanced pad pressure and consistent pedal feel.

Key Engineering Features

• Compound Rotor Construction: The friction ring is cast iron, but the central “hat” (hub) is aluminum. They are connected by steel pins, allowing the rotor to expand and contract radially under extreme heat without warping.

• Unsprung Weight Reduction: By using aluminum monoblock calipers and compound rotors, this system significantly reduces unsprung mass compared to standard single-piston sliding calipers, improving suspension response.

• Directional Ventilation: The internal vanes of the rotors are curved to act as a centrifugal pump, pulling cool air from the center of the hub and exhausting it through the outer edge.

Professional Installation & Cataloging Notes

1. Retrofit Requirements (Coding): If installing this set on a non-M car (e.g., F30 335i), the vehicle’s DSC (Dynamic Stability Control) must be coded to Option 2NH (M Sport Brakes). This recalibrates the brake bias and ensures the master cylinder provides the correct pressure for the multi-piston setup.

2. Wheel Clearance: This set requires a minimum of 18-inch wheels. Note that some 18″ aftermarket wheels with heavy barrel profiles may still interfere with the front 4-piston calipers.

3. Brake Shield Modification: If retrofitting to a standard F22 or F30, the original dust shields may need to be trimmed or replaced with M-specific shields to accommodate the larger $380\text{mm}$ front rotors.

4. Hardware: The caliper-to-carrier bolts are one-time use stretch bolts. For “As New” installation, always use fresh mounting hardware torqued to $30\text{ Nm} + 90\text{°}$ (Front) and $30\text{ Nm} + 90\text{°}$ (Rear).
