SP Performance S55-166-BP Double Drilled & Slotted Performance Rotor Set Black Zinc

The SP Performance S55-166-BP Double Drilled & Slotted Rotors deliver maximum cooling and cleaning power for high-performance braking applications. Featuring dual sets of precision-drilled holes that enhance airflow and heat dissipation, combined with machined slots that continuously remove brake dust, gases, and water from the braking surface for cleaner, more consistent pad contact.

Key Features:

• Dual drilled hole pattern maximizes airflow and heat dissipation during extreme braking
• Machined slots sweep away brake dust, gases, and water for optimal pad-to-rotor contact
• Exclusive Sinusoid Curve Chamfer increases air circulation while eliminating sharp edges and minimizing rotor stress
• Black zinc-coated finish provides corrosion resistance and aggressive appearance
• Premium rotor construction resists heat buildup, warping, and thermal cracking
• Slotted design channels water away from braking surface to prevent hydroplaning in wet conditions
• Reduces brake fade and extends the life of both rotors and brake pads
• Sold as a pair for convenient replacement

Engineered for enthusiasts who demand superior stopping power under extreme conditions, these rotors combine advanced cooling technology with durable construction. The precision-drilled hole pattern and slot design work together to maintain optimal braking temperatures, reduce the risk of heat checking, and deliver consistent, reliable performance on the street or track. Backed by SP Performance's lifetime warranty against manufacturing defects.
