CORINTH Drilled Brake Rotor Set | Front Axle High Performance Brake Rotors - KLT363620A

· Cross-Drilled Cooling Hole Design: Precision-drilled holes across the friction surface increase airflow, improve heat dissipation and allow hot brake gas and water to escape from the pad-rotor interface, reducing brake fade and improving wet-weather braking performance.

· Enhanced Thermal Capacity: The drilled design significantly increases the rotor's surface area and cooling efficiency, maintaining consistent friction performance during repeated hard braking, spirited driving and performance-oriented use.

· High-Quality Cast Iron Construction: Manufactured from premium G3000 or optional high-carbon cast iron providing excellent structural integrity, thermal stability and crack resistance, suitable for performance driving conditions that generate elevated brake temperatures.

· Anti-Corrosion Zinc Coating: Non-friction surfaces including the interior of drilled holes receive a zinc-based protective coating that prevents rust and corrosion, maintaining both structural integrity and clean appearance behind performance alloy wheels.

· Direct OE Fitment & Balanced: Precision machined to exact OE dimensions for direct replacement with factory calipers, and dynamically balanced for vibration-free high-speed braking, compatible with performance-oriented brake pad compounds.

Product Overview

CORINTH drilled brake rotors feature precision cross-drilled holes across the friction surface, providing enhanced cooling, improved wet-weather braking and gas evacuation for performance-oriented vehicles. Designed as a direct-fit upgrade from standard plain rotors, these drilled discs deliver measurable improvements in heat dissipation and braking consistency for spirited driving.

Core Performance Advantages

· Cross-Drilled Cooling Hole Design: Precision-drilled holes across the friction surface increase the rotor's effective cooling surface area and improve air circulation around and through the disc. This enhanced cooling reduces operating temperatures during hard braking, helping to resist brake fade and maintain consistent friction performance during spirited driving.

· Improved Wet Weather Braking: The drilled holes allow water to escape from the pad-rotor interface quickly, reducing the risk of hydroplaning between the pad and rotor surface. This restores braking performance faster after driving through rain, puddles or wet conditions, improving safety and confidence in wet weather.

· Hot Gas Evacuation: During heavy braking, brake pads can release gases that create a barrier between the pad and rotor surface, reducing effective friction. Drilled holes provide venting paths for this gas to escape, maintaining consistent pad contact and friction coefficient under performance driving conditions.

· High-Quality Cast Iron Construction: Manufactured from premium G3000 or optional high-carbon cast iron with chamfered drill holes that reduce stress concentrations and resist cracking. The material provides excellent structural integrity and thermal stability suitable for performance driving conditions.

Application & Usage

· Suitable Vehicle Types: Sport sedans, performance coupes, hot hatches, tuned vehicles and SUVs used for spirited driving. Suitable as an upgrade for any vehicle where improved brake cooling is desired.

· Operating Conditions: Ideal for spirited street driving, canyon roads, mountain driving, occasional track days and wet weather performance. Not recommended for dedicated heavy track use without high-carbon material upgrade.

· Expected Service Life: 40,000–60,000 km under normal mixed driving conditions. Aggressive driving may shorten service life.

· Installation: Direct OE replacement with no modification required. Compatible with factory calipers. Best paired with performance-oriented brake pads. Follow proper bedding-in procedure.
