StopTech AeroRotor Replacement Kits (ARK) offer major benefits compared to original factory brake rotors. The AeroRotor vanes pushes up to 80% more air than factory rotors for better cooling and reduced fade. Designed for BMW F80 F82 F83 M3 & M4.

The 2 piece brake discs offers a significant improvement over standard, suitable for those who doesn't require a BBK. 

Typical OEM brakes are designed for cars with standard engines, performing routine tasks: the morning and evening commute, grocery shopping, driving the kids to soccer practice, etc. In other words, your OEM brakes can easily become overwhelmed.

Performance rotors are direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the OE rotors just don't offer.

Slotting and/or cross-drilling helps wipe away the debris that forms between the pad and the disc, adds more bite, and can help the rear brakes to match the aesthetics of a front big brake kit. The rotor finish helps prevent glazing of the pads and improves wet and dry braking performance.

The primary purpose of 2-piece rotors is to reduce unsprung and overall vehicle weight. This is accomplished by using two-piece disc construction. The 2-piece design also allows for independent expansion of the rotor and hat without coning. The secondary purpose is to increase the ventilation and cooling capacity of the brake disc. Better airflow means better cooling and less fade.
