Product Overview

CORINTH premium OE brake rotors represent the highest tier of replacement brake disc quality, engineered and manufactured to match or exceed original equipment standards. Using premium cast iron materials, ultra-tight machining tolerances, enhanced anti-corrosion coating and rigorous multi-stage quality validation, these rotors are designed for the premium aftermarket segment and discerning vehicle owners.

Core Premium Advantages

· Premium Cast Iron & Material Control: The G3000 cast iron is sourced and processed with tighter material specification controls, ensuring consistent carbon content, hardness, microstructure and tensile strength across every production batch. This material consistency translates to predictable friction performance, uniform wear and long-term structural stability.

· Ultra-Tight Dimensional Tolerances: Premium rotors are machined to stricter-than-industry-standard tolerances for thickness variation (under 0.005mm), lateral runout, flatness and surface finish. This level of precision ensures perfect pad-to-rotor contact, eliminates brake judder and delivers the smooth, refined, vibration-free braking feel expected from premium and luxury vehicles.

· Enhanced Anti-Corrosion Coating: A high-quality protective coating is applied to all non-friction surfaces including internal cooling vanes, hub face, bolt holes and outer edges. The coating provides superior rust resistance compared to standard paint or zinc plating, maintaining clean appearance behind open-spoke alloy wheels and preventing corrosion-related cooling degradation.

· Multi-Stage Quality Validation: Every premium rotor undergoes dimensional inspection, dynamic balancing, surface finish verification, hardness testing and visual quality checks. Only rotors that pass all validation stages proceed to premium packaging, ensuring consistent top-tier quality across every unit and every production batch.

Application & Usage

· Suitable Vehicle Types: Premium sedans, luxury vehicles, modern SUVs, European cars and any application where OE-equivalent-or-better quality is expected or required.

· Operating Conditions: All normal driving conditions with particular benefit in vehicles where braking refinement, smoothness and corrosion resistance are priorities.

· Expected Service Life: 60,000–80,000 km under normal driving conditions, with corrosion protection lasting well beyond the friction material service life.

· Installation: Direct OE replacement. Premium packaging includes protective wrapping and clear axle-position labeling.

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). Our technical team will match it accurately against our comprehensive catalog database, typically within one working day, and confirm fitment including front/rear axle position and wheel size compatibility.

Q: What is the lead time for bulk orders?

A: Stock items ship within 7–10 working days from order confirmation. Mass production orders with custom branding or specifications typically require 20–30 working days, depending on order volume and complexity. Rush production can be arranged for urgent orders — please contact our sales team to discuss feasibility and any associated expediting fees.

Q: Can I get samples before placing a bulk order?

A: Absolutely. We encourage customers to evaluate quality firsthand. Samples are available for performance testing and dimensional verification; the buyer covers shipping costs, and samples dispatch within 3–5 working days. For confirmed bulk orders, sample fees can be credited back against your first purchase order as a goodwill gesture.

Q: What is your warranty policy?

A: We offer a 12-month / 50,000 km warranty against manufacturing defects under normal driving conditions and professional installation. This covers material defects, cracking, and abnormal wear attributable to production. Warranty claims are processed efficiently with photo documentation and lot number traceability, and replacement or credit is issued promptly upon verification.

Q: What types of brake discs do you offer?

A: Our range covers solid discs for standard passenger vehicles, vented discs for improved heat dissipation, drilled and slotted performance discs for sport and heavy-duty applications, and anti-rust Geomet-coated options for corrosion-prone markets.
