Advanced Technology ® Police Rotors

Law Enforcement agencies demand performance, stealth and dependability in the patrol vehicles they operate on city and streets. With that in mind, Raybestos brand "Quiet on Arrival" (QOA ® ) Advanced Technology ® rotors are engineered for superior performance and deliver unmatched stopping power cooling properties ad noise control .
Superior Metallurgy

Our dedicated engineers have improved upon the "one metallurgy fits all" theory. QOA Technology rotors are cast from damped iron – an alloy that is metallurgically formulated to disrupt vibration and suppress noise ensuring consistent and quiet arrivals every time.

Enhanced Vane Configuration

Specifically designed for increased air flow throughout the rotor, the QOA rotor maintains lower temperatures with a vane configuration no other competitive rotor in the market can match.



Optimized Weight

When police vehicles make sudden high-speed stops, weight distribution and temperatures are inherently high on the front wheels. Recent fleet testing has reveled a replacement ratio of 3:1 between front and rear rotor. Raybestos QOA Advanced Technology rotors used on both the front and the rear provide outstanding braking characteristics and performance whether on patrol or in pursuit.

Coat Armor

Subjected to environmental conditions such as heat, cold, ice, snow and rain, durability is a critical aspect of police rotors. This polymer binding coating has special armor-type shielding characteristics that provide significantly greater protection against the elements.

Police specific vane configuration enhances cooling air flow throughout the rotor allowing for optimal dissipation – something quite important during pursuit driving This advanced polymer coating is evenly applied on every rotor using state of the art robotic technology

Heat Dissipation


Raybestos brand police rotors featuring "Quiet on Arrival" (QOA) technology are the ultimate performance solution for today’s Law Enforcement vehicles.
