SP Performance S55-2176-BP Drilled and Slotted Brake Rotor with Black Zinc Coating

The SP Performance S55-2176-BP is a high-performance drilled and slotted brake rotor featuring a corrosion-resistant black zinc coating. This rotor combines the cooling benefits of cross-drilled holes with the gas and dust expulsion advantages of directional curved slots, delivering enhanced braking performance for demanding driving conditions.

Key Features:

• Cross-drilled holes machined with exclusive sinusoid curve chamfer for maximum cooling and minimal stress concentration
• Directional curved slots increase pad bite, improve air circulation, and help expel brake gases and dust
• Black ZRC (Zinc Rich Coating) provides superior corrosion resistance and a clean appearance behind your wheels
• Manufactured from premium quality castings that exceed OEM specifications
• CNC-machined and CAD-designed for consistent, high-quality performance
• Chamfered drill holes eliminate sharp edges to reduce heat checking and extend rotor and pad life
• Slots help reduce brake fade and improve wet weather stopping performance

SP Performance rotors are engineered to handle the heat and stress generated during aggressive braking. The combination of drilled holes and directional slots provides optimal cooling while keeping the rotor surface clean for consistent pad contact and reliable stopping power.
