SP Performance S55-171-BP Double Drilled Slotted Brake Rotors Zinc Coated - Black Pair

The SP Performance S55-171-BP Double Drilled & Slotted Performance Rotors deliver exceptional cooling and cleaning capabilities for demanding braking applications. These high-performance rotors feature dual sets of precision-drilled holes that enhance airflow and accelerate heat dissipation, while machined slots continuously remove brake dust, gases, and moisture to maintain consistent pad contact.

Advanced Engineering:

• Dual drilled hole patterns maximize air circulation and thermal management
• Machined slots sweep away debris, gases, and water for cleaner braking surfaces
• Exclusive Sinusoid Curve Chamfer on each drilled hole increases airflow while eliminating sharp edges
• Black zinc coating provides corrosion resistance and an aggressive appearance
• Premium materials resist warping and heat checking under extreme conditions

Performance Benefits:

• Superior heat dissipation reduces brake fade during hard stops
• Slotted design channels water away to prevent hydroplaning in wet conditions
• Reduced rotor stress extends service life of both rotors and brake pads
• Sinusoid chamfering minimizes stress concentrations to prevent cracking

Sold as a pair and backed by a lifetime warranty against manufacturing defects. These rotors combine track-proven technology with street-friendly durability for drivers who demand maximum stopping power.
