CORINTH Drilled & Slotted Brake Rotor Kit | Front & Rear Performance Upgrade - KLT325595

· Combined Drilled & Slotted Design: Merges cross-drilled cooling holes with precision performance slots to deliver the maximum benefits of both technologies — superior heat dissipation from drilling plus enhanced pad bite and gas evacuation from slotting.

· Maximum Cooling & Fade Resistance: Drilled holes increase surface area and airflow while slots channel hot gas away, together reducing operating temperatures significantly and providing exceptional resistance to brake fade during aggressive driving and repeated hard stops.

· Consistent Pad Surface Renewal: The slots continuously clean and de-glaze the brake pad surface, maintaining maximum friction coefficient and sharp pedal response throughout the service life of the pads, even under heavy performance use.

· High-Carbon Material Option: Available in premium high-carbon cast iron for enhanced thermal stability and crack resistance under extreme performance conditions, recommended for serious performance driving, track days and heavy-duty applications.

Zinc Coated & Precision Balanced: All non-friction surfaces including hole interiors are zinc-coated for rust prevention, and each rotor is dynamically balanced for smooth, vibration-free high-speed operation with direct OE fitment for easy upgrade installation.

Product Overview

CORINTH drilled and slotted brake rotors combine both performance surface treatments into one premium upgrade, delivering the maximum benefits of cooling holes and performance slots. These rotors provide superior heat dissipation, enhanced pad bite, improved gas evacuation and consistent friction performance, making them the ideal choice for serious performance street driving and light track use.

Core Combined Performance Advantages

· Maximum Cooling from Drilled Holes: Cross-drilled holes increase the rotor's cooling surface area, improve air circulation and allow heat to dissipate more effectively than plain or slotted-only rotors. This enhanced cooling reduces operating temperatures during repeated hard braking, significantly improving fade resistance for performance driving.

· Enhanced Pad Bite from Slots: Precision-machined slots continuously clean the brake pad surface, remove glaze and transfer material, and create a mechanical biting action that increases initial brake response and friction coefficient. The slots also provide additional gas evacuation paths for consistent pad contact under heavy braking.

· Superior Wet Weather Performance: The combination of drilled holes and slots provides multiple paths for water to escape from the pad-rotor interface, restoring braking performance quickly in wet conditions and reducing the initial spongy feel that can occur with plain rotors in rain.

· High-Carbon Material Option: Available in premium high-carbon cast iron for enhanced thermal stability, improved crack resistance and better heat dissipation — recommended for serious performance driving, track days and vehicles with increased power or weight. Standard G3000 option available for street performance use.

Application & Usage

· Suitable Vehicle Types: High-performance cars, sport sedans, muscle cars, tuned vehicles, performance SUVs and any application where maximum braking performance upgrade is desired.

· Operating Conditions: Spirited street driving, canyon carving, mountain roads, track days, motorsport events and wet weather performance driving.

· Expected Service Life: 35,000–55,000 km under normal mixed driving. Performance and track use will reduce service life. Monitor slot and hole condition regularly.

· Installation: Direct OE replacement with no modification. Compatible with factory calipers. Best paired with performance brake pads. Proper bedding-in is critical for drilled and slotted rotors.
