Alcon Pro System MK5 GTI Front Race Kit.

SCCA approved kit for 2004-2009 VW GTI

Benefit from racing supremacy with the Alcon/Pro System Big Brake Kit Front for the VW GTI! Born from decades experience, this kit is a fusion of performance and precision. Crafted in collaboration with performance shops, it is cutting-edge braking technology. Tailored for aftermarket wheels or OEM wheels, envision conquering corners with 332mm  x 32mm rotors and 4 Piston Alcon competition calipers, redefine braking perfection.  Curved directional slots and vanes for maximum cooling and performance.

Caliper Features:

• Radial mount for maximum rigidity and firm, consistent pedal
• Differential piston diameters to minimize pad taper wear
• Aluminium pistons as standard, stainless steel pistons available as an option to reduce heat transfer to brake fluid
• 2kg anti-knock back springs
• Hard stainless steel wear plates
• Fixed pad retainer

Features

• All rotors are machined at our facility in Mooresville, North Carolina from specially formulated grey cast iron providing the best in thermal stability, friction coefficient and heat transfer characteristics.
• Dyno-bedded rotors and pads
• Precision machined and anodized aluminum hats and brackets
• Fully floating rotor attachment with anti-rattle clips
• Added value, most of our competitor's kits have a similar cost but brake pads, anti-rattle clips and bedding are not included. However, these are all included.

Rotors

• 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.

Aluminum Hats

• CNC machined from lightweight 6061-T6 aerospace grade aluminum
• Unsprung weight reduction
• High strength and durability
• Black/hard anodized to increase resistance to wear and corrosion
