SP Performance S55-2128-BP SP Performance Double Drilled & Slotted Performance Rotor Set, Black Zinc Coated

The SP Performance S55-2128-BP Double Drilled & Slotted Performance Rotors deliver maximum cooling and cleaning power for high-performance braking applications. These premium rotors feature dual sets of precision-drilled holes that enhance airflow and accelerate heat dissipation, while machined slots continuously remove brake dust, gases, and water to maintain cleaner, more consistent pad contact.

Advanced Design Features:

• Dual drilled hole pattern maximizes airflow for superior heat management
• Precision-machined slots evacuate debris, gases, and water from braking surface
• Exclusive Sinusoid Curve Chamfer increases air circulation and eliminates sharp edges
• Black zinc-coated finish provides corrosion resistance and aggressive appearance
• Premium casting materials resist warping and heat checking under extreme conditions

Performance Benefits:

• Reduces brake fade during aggressive driving and towing
• Minimizes rotor stress and extends component life
• Channels water away from braking surface to prevent hydroplaning
• Extends brake pad longevity through reduced heat buildup
• Delivers reliable, consistent stopping power under extreme braking

Sold as a pair of rotors. Each rotor features SP Performance's signature Sinusoid Curve Chamfer drilling technique, which reduces the risk of stress cracking and warping while promoting optimal air circulation. Backed by a lifetime warranty against manufacturing defects.
