StopTech BMW F80 F82 F83 M3 M4 2-Piece Aero Front Brake Discs - Pair
Upgrade the front brakes on your BMW M3 or M4 with StopTech AeroRotor Replacement Kits. These 2-piece Aero front brake discs are a direct replacement for the factory front rotors on BMW F80 M3, F82 M4 and F83 M4 models, retaining OEM dimensions while delivering serious performance gains. The StopTech AeroRotor vane design pushes up to 80% more air than factory rotors for improved cooling, reduced brake fade and dependable stopping power on fast road and track day use.
If you want a real-world brake upgrade without committing to a big brake kit, these two-piece front brake discs are the perfect solution. They reduce unsprung mass, manage heat more effectively and maintain the stock calipers for straightforward installation and everyday drivability.

Real benefits you can feel
Slotting and cross-drilling options help clear pad debris, maintain a clean contact patch and add initial bite. The rotor finish helps reduce pad glazing and supports consistent wet and dry braking performance. The floating 2-piece design also allows the rotor ring and hat to expand independently, helping minimise coning and improving thermal stability during spirited driving.
