SP Performance D52-544-BP Diamond Slotted Brake Rotor with Zinc Plating - Black

The SP Performance D52-544-BP Diamond Slotted Brake Rotor combines innovative diamond dimple technology with directional curved slots to deliver superior braking performance and distinctive style. This high-performance rotor is designed as a direct replacement for OEM rotors, requiring no brake system modifications.

Diamond Slotted Design:

• Unique diamond dimples create recesses to dampen expanding gasses that push against brake pads
• Directional curved slots expel brake dust, heat, and gasses away from the braking surface
• Chamfered diamond edges eliminate stress concentration points to reduce cracking risk
• Enhanced brake pad bite for improved stopping power in all weather conditions
• Prevents brake hydroplaning in wet weather by channeling water away from contact surfaces

Premium Construction:

• Manufactured from high-strength cast iron that exceeds OEM specifications
• Black zinc plating (BP) provides corrosion resistance and a distinctive appearance
• CNC-machined and CAD-designed for precise fitment and consistent performance
• Machine balanced and disc ground to ensure smooth, vibration-free operation
• Machined and plated to order by SP Performance employees in the USA

Performance Benefits:

• Maximizes air circulation for effective cooling to prevent brake fade
• Reduces brake dust buildup on wheels and rotor surfaces
• Increases pad contact and bite for shorter stopping distances
• Extends rotor and brake pad life through efficient heat dissipation
• Maintains structural integrity under heavy braking conditions

SP Performance pioneered diamond slotting technology, creating a design that maximizes performance while maintaining rotor structural integrity. The combination of diamond dimples and directional slots provides superior gas venting and cooling compared to traditional slotted-only designs, helping eliminate brake fade during demanding driving situations.
