Alcon/Pro System Porsche 992 GT3 Brake Kit Replacement Rotor Rings

Alcon has taken what it has learned during more than two decades in motorsport to develop brake kits and solutions for selected street machines. These upgrades allow high-performance vehicles to take on both track and road challenges. 

Replacement 390mm x 36mm rotors.  (Specify left or right)   This part is the RING only and does not include hats or hardware.

Features

• All rotors are machined at our facility in Mooresville, North Carolina from specially formulated materials providing the best in thermal stability, friction coefficient and heat transfer characteristics.
• Dyno-bedded  No bedding or shudder issues!

• Floating 2-piece design allows thermal expansion of the rotor while minimizing deformation and ensuring the rotor is self-centered with the pads
• Superior braking and cooling efficiency
• Features directional ventilation vanes to create suction, turbulence, and guides cool air through the rotor for improved heat dissipation and increased resistance to cracking

Curved Directional Ventilation Vanes

Features 48 directional ventilation vanes to create suction and turbulence, and guide cool air through the rotor to achieve better heat dissipation and increased resistance to cracking under harsh track conditions. Each rotor is left or right side specific, and the ventilation vanes are optimized to spin in a particular direction to pump the maximum amount of cool air through the rotor. This design allows the rotor to run up to 30% cooler than O.E. rotors and increases cooling efficiency by up to 30% over standard 1-piece units. Brake fade and judder are minimized during extended sessions. This means the brake system can withstand heavier track usage and provide consistent braking performance lap after lap.

Slotted Friction Face

Slotted rotor face pattern improves brake consistency by constantly cleaning the contact surface and dissipate heat generated, and gases released when the pads come into contact with the rotors. Slotted rotors have a superior advantage over blank rotors in wet or raining conditions by preventing water films to form between the brake pad and rotor surface.
