Directional Slot Geometry: Features angled slots designed to work with rotor rotation, helping sweep away brake dust, road debris and hot gas from the pad contact zone for improved braking consistency.
Left/Right Specific Design: Manufactured as dedicated left and right versions to ensure the directional slots face the correct rotation direction, maximizing debris clearance and performance benefit.
Continuous Pad Surface Refreshment: The angled slot edges continuously clean and refresh the brake pad surface, removing glazed material and maintaining consistent friction coefficient throughout pad service life.
G3000 Cast Iron Construction: High-quality G3000 gray cast iron provides stable friction performance, excellent thermal conductivity and durable wear resistance for reliable daily and performance use.
Precision Balanced & Zinc Coated: Dynamically balanced for smooth, vibration-free operation and protected by a full zinc coating against rust and corrosion in wet, salty or humid environments.

Product Overview
CORINTH directional slotted brake rotors use angled slot geometry to improve debris and gas clearance between the brake pad and rotor. Unlike straight or curved non-directional slots, these rotors are designed with rotation-specific slot angles that help channel contaminants outward as the rotor spins. This makes them particularly effective in conditions involving dust, water and heavy brake gas buildup.
Core Performance Advantages
Rotation-Optimized Debris Clearance: Directional slots are angled to move brake dust, road debris and hot gas away from the pad contact area as the rotor rotates. This reduces the chance of contaminants becoming trapped between the pad and rotor, which can cause inconsistent friction, noise and uneven wear. The result is cleaner contact surfaces and more consistent braking performance.
Improved Wet Weather Performance: The directional slot design also helps channel water away from the friction surface during wet braking. By breaking through the water film and providing escape paths, the slots help restore friction more quickly after the brake pedal is applied, reducing initial brake lag in rainy conditions.
Left/Right Specific Fit: Because the slots are directional, correct installation is important. These rotors are clearly designated for left or right side use, ensuring the slot angles face the intended rotation direction. When installed correctly, they provide maximum debris clearance, gas evacuation and braking consistency.

Frequently Asked Questions
Q: What certifications do your brake discs have?
A: Our manufacturing facility operates under the IATF 16949 quality management system — the global automotive industry standard for quality and continuous improvement. The majority of our mainstream brake disc models are ECE R90 approved for the European market, and AMECA certification is available on request for North American applications. All test reports and certification documents are available for review upon inquiry.
Q: Do you offer OEM / private label service?
A: Yes, full OEM and private label solutions are available. We support custom logo laser engraving or printing, branded packaging design, custom part numbering, and tailored performance specifications — including friction material pairing, coating options, and dimensional fine-tuning. Our engineering team works directly with you from design review through first-article inspection to ensure your branded product meets your exact requirements.
Q: What is your minimum order quantity?
A: For stock models, the MOQ is just 20 pieces per size, making it easy to test market demand. Custom branded OEM orders start at 300 pieces per model. Mixed-container orders across multiple part numbers are also supported to help you optimize shipping costs and inventory breadth. Small trial orders are welcome for new customers.
Q: How do I find the correct brake disc model?
A: Simply send us any of the following: the OE part number, a competitor's cross-reference number, or full vehicle details (brand, model, year, and chassis/VIN number).
