SP Performance S55-2135-R Double Drilled Slotted Brake Rotors Zinc Coated - Red

The SP Performance S55-2135-R Double Drilled & Slotted Performance Rotors deliver superior cooling and cleaning capabilities for demanding braking applications. This rotor set features dual precision-drilled hole patterns that enhance airflow and accelerate heat dissipation, while machined slots continuously sweep away brake dust, gases, and moisture to maintain consistent pad-to-rotor contact.

Key Features:

• Dual drilled hole sets maximize air circulation and thermal management
• Machined slots remove debris, gases, and water for cleaner braking surface
• Exclusive Sinusoid Curve Chamfer on drilled holes increases airflow while eliminating sharp edges
• Premium rotor material resists heat checking, cracking, and warping under extreme conditions
• Red zinc coating protects against corrosion while providing aggressive styling
• Slotted channels reduce hydroplaning risk in wet conditions by directing water away from contact surface
• Advanced thermal design reduces brake fade and extends pad life
• Sold as a pair for complete axle replacement

The Sinusoid Curve Chamfer technology represents a significant engineering advancement, reducing rotor stress concentration points that lead to premature failure. By smoothing the transition around each drilled hole, this design minimizes heat-related damage while promoting optimal air circulation. Each rotor is manufactured from high-quality materials engineered to withstand repeated heat cycling without dimensional changes. Backed by SP Performance's lifetime warranty against manufacturing defects, these rotors provide reliable performance for street, track, and high-performance driving applications.
