CORINTH Drilled Brake Rotor Set | Front Axle High Performance Brake Discs - KLT365750

· Front Axle Matched Pair Set: Contains two front brake rotors precision-matched for left and right sides, ensuring balanced braking performance, equal wear rate and consistent pedal feel across the front axle.

· Cross-Drilled Cooling Design: Strategically drilled holes increase heat dissipation surface area, lowering peak operating temperatures during hard braking and reducing the risk of front brake fade under heavy load or spirited driving.

· G3000 Gray Cast Iron Construction: Manufactured from high-grade G3000 gray cast iron with stable friction characteristics, excellent thermal conductivity and durable wear resistance for long service life.

· Zinc Anti-Corrosion Coating: Full-surface zinc coating protects against road salt, moisture and rust, maintaining both structural integrity and clean appearance through seasonal changes.

· Direct OE Fitment: CNC machined to exact original equipment dimensions, including diameter, thickness, bolt pattern, hub bore and offset, enabling straightforward bolt-on installation without modification.

Product Overview

CORINTH front axle drilled brake rotor set provides a complete high-performance cooling upgrade for vehicle front brakes. Since front brakes typically handle the majority of deceleration load, upgrading front rotors delivers one of the most noticeable improvements in braking consistency and fade resistance. This set includes a matched left-and-right pair of cross-drilled rotors, engineered to improve cooling performance while maintaining direct OE compatibility.

Core Performance Advantages

  • Front Axle Cooling Upgrade: Front brakes usually generate more heat than rear brakes, especially during hard braking, downhill descents and high-speed driving. The cross-drilled design increases surface area for heat dissipation, helping front brakes operate within a more stable temperature range. This reduces the likelihood of brake fade and maintains more consistent stopping power during demanding conditions.

  • Matched Pair Balance: Both rotors in the set are precision-machined and balanced as a front axle pair. This helps ensure equal braking effort between the left and right front wheels, reducing the risk of brake pull, uneven pad wear and vibration. For drivers upgrading front brakes, a matched set is critical to achieving smooth, predictable braking behavior.

  • Durable Daily Performance: Made from G3000 gray cast iron, these rotors balance performance and durability for everyday driving. The drilled pattern improves cooling without compromising the structural reliability required for regular commuting, highway driving and occasional performance use.

Application & Vehicle Compatibility

Suitable for front axle replacement on sedans, hatchbacks, coupes, SUVs and light trucks. Compatible with all major global vehicle brands including Toyota, Honda, Ford, Volkswagen, BMW, Mercedes-Benz, Audi, Nissan, Chevrolet and Hyundai. Designed for direct bolt-on installation with original calipers, hubs and wheel assemblies. Recommended for use with front brake pads suited to drilled rotor applications.

Quality Assurance & Certification

Manufactured in IATF 16949 certified facilities with strict process control. Each rotor undergoes 100% dimensional inspection, dynamic balance testing, surface hardness verification and visual crack inspection. ECE R90 certification is available for applicable European vehicle models. Full batch traceability documentation is provided with every wholesale order.


Precision Manufacturing

Advanced CNC machinery and automated production lines deliver micron-level accuracy on every brake component, ensuring consistent fit and performance across the entire product range.

OE-Standard Quality Control

Every batch undergoes rigorous inspection — from raw material testing to final dimensional verification — matching original equipment specifications for reliability you can trust.

High-Efficiency Production Capacity

Streamlined workflows and smart factory scheduling enable large-volume order fulfillment without compromising lead times or product consistency.

Certified Compliance

Manufactured under IATF 16949 certified processes with ECE R90 and AMECA validated products, meeting global regulatory standards for safety and durability.

End-to-End Traceability

Full production data tracking from forging to packaging gives complete quality transparency and rapid issue resolution at every stage.
