SP Performance T18-539-P Slotted Brake Rotors with Zinc Plating - Silver Left and Right Pair

The SP Performance T18-539-P slotted brake rotors deliver a direct-fit, performance upgrade over standard OEM disc brakes. Sold as a matched left and right pair, these vented rotors feature precision-machined directional slots and a bright silver zinc (ZRC) anti-corrosion coating for a clean, show-quality appearance behind any wheel.

Key Features:

• Directional Angled Slots – Increase pad bite, improve air circulation, and channel heat away from the rotor surface, reducing brake fade and stopping distances
• Directional Mini Half Slots – Balance and stabilize friction levels while optimizing pad-to-rotor contact across the full sweep area
• Bright Silver Zinc (ZRC) Anti-Corrosion Coating – Protects the hat, vanes, and non-contact surfaces from rust, corrosion, and oxidation for a long-lasting clean look
• Machine Balanced & Disc Ground – Every rotor is machine balanced and disc ground to meet or exceed OEM specifications, eliminating vibration and pedal pulsation
• CNC Machined from Premium Castings – Designed with CAD software and produced on CNC equipment for consistent dimensions and performance batch to batch
• Direct OEM Replacement – Bolt-on installation with no brake system modifications required
• Made in the USA – Machined and plated to order by SP Performance employees
• Sold as a Pair – Includes both left and right rotors for a complete axle-end replacement

Slotted rotors are the preferred rotor style for performance driving and demanding use. The slots continuously sweep the brake pad surface clean of gases and debris, maintaining a firm, consistent bite even during repeated hard stops. SP Performance rotors are warrantied to be free of defects in workmanship and are guaranteed not to crack for the life of the rotor.
