SP Performance S55-159-BP Double Drilled Slotted Brake Rotors Zinc Coated - Black Pair

SP Performance S55-159-BP Double Drilled & Slotted 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 for cleaner, more consistent pad contact.

Advanced Sinusoid Curve Chamfer Technology:

Each rotor is precision-drilled with SP Performance's exclusive Sinusoid Curve Chamfer design, which increases air circulation throughout the rotor, eliminates sharp edges that can cause stress concentrations, and minimizes thermal stress. This innovative design reduces the risk of heat checking, cracking, and warping while extending the service life of both the rotors and brake pads.

Key Features:

• Dual drilled hole pattern for maximum airflow and heat dissipation
• Machined slots remove brake dust, gases, and water from braking surface
• Sinusoid Curve Chamfer eliminates sharp edges and reduces rotor stress
• Black zinc-coated finish for corrosion resistance and aggressive appearance
• Premium materials resist warping under extreme braking conditions
• Slotted design channels water away to prevent hydroplaning in wet conditions
• Reduces brake fade during high-performance driving
• Extends brake pad longevity through improved contact and reduced heat

Sold as a pair and backed by SP Performance's lifetime warranty against manufacturing defects. These rotors are crafted from premium materials and engineered to deliver reliable, consistent stopping power under the most demanding conditions while providing an aggressive, performance-oriented look.
