CORINTH Cross Drilled Brake Discs | Better Heat Dissipation Auto Brake Rotors - KLT325490B

· Cross-Drilled Heat Dissipation Design: Precision cross-drilled holes create additional cooling surface area and improve air circulation across the friction surface, effectively dissipating heat generated during hard braking and reducing the risk of brake fade.

· Enhanced Wet Weather Braking: The drilled holes allow water to escape from the pad-rotor interface quickly, reducing the risk of hydroplaning between pad and rotor and restoring braking performance faster after driving through wet conditions.

· Gas Venting for Consistent Friction: During heavy braking, brake pads can release gas that creates a barrier between pad and rotor. Cross-drilled holes provide venting paths for this gas, maintaining consistent pad contact and friction coefficient under performance conditions.

· High-Quality Cast Iron Construction: Manufactured from premium G3000 or high-carbon cast iron with precision-drilled holes that are chamfered or deburred to prevent stress cracking, ensuring structural integrity and long service life under performance use.

Anti-Corrosion Coated & Balanced: Zinc-based protective coating on all non-friction surfaces including hole interiors, with dynamic balancing for vibration-free operation. Direct OE dimensions for straightforward performance upgrade installation.

Product Overview

CORINTH cross-drilled brake rotors feature precision-drilled holes arranged in a cross-pattern across the friction surface, providing enhanced heat dissipation, improved wet-weather braking and gas evacuation for performance-oriented vehicles. The cross-drilled pattern optimizes cooling while maintaining structural integrity for reliable performance upgrade use.

Core Technical Advantages

· Cross-Pattern Drilling Design: Holes are arranged in a precision-engineered cross or staggered pattern across the friction surface, optimizing cooling coverage while maintaining structural integrity. The pattern ensures even heat distribution and consistent pad contact across the entire braking surface, avoiding hot spots that can cause uneven wear or cracking.

· Enhanced Heat Dissipation: The drilled holes significantly increase the rotor's effective cooling surface area and improve air circulation through and around the disc. This enhanced cooling reduces peak operating temperatures during hard braking, helping to resist brake fade and maintain consistent friction performance during spirited driving.

· Gas & Water Venting: Cross-drilled holes provide efficient venting paths for hot brake gas generated during heavy braking, preventing gas-induced fade. The holes also allow water to escape quickly from the pad-rotor interface in wet conditions, restoring braking performance faster than plain rotors.

· High-Quality Cast Iron with Chamfered Holes: Manufactured from premium G3000 or high-carbon cast iron with chamfered or deburred drill holes that reduce stress concentrations at the hole edges. This design detail helps prevent crack initiation and extends rotor service life under performance driving conditions.

Application & Usage

· Suitable Vehicle Types: Performance cars, sport sedans, coupes, hot hatches, tuned vehicles and SUVs used for spirited driving. Popular for European performance car upgrades.

· Operating Conditions: Spirited street driving, highway operation, wet weather performance and mountain driving. Suitable for occasional track day use with high-carbon material option.

· Expected Service Life: 40,000–60,000 km under normal mixed driving conditions.

· Installation: Direct OE replacement. Compatible with factory calipers. Best paired with performance ceramic or semi-metallic brake pads. Proper bedding-in procedure recommended.
