SP Performance S54-5143-R SP Performance Double Drilled & Slotted Performance Rotor Set, Red Zinc Coated

The SP Performance S54-5143-R Double Drilled and Slotted Brake Rotor delivers superior stopping power and enhanced cooling performance for demanding driving conditions. Manufactured in the USA, this performance rotor features SP Performance's exclusive sinusoid curve chamfer drilling technology that eliminates sharp edges to reduce stress concentrations and prevent cracking while maximizing heat dissipation.

Key Features:

• Cross drilled holes with sinusoid curve chamfer for optimal cooling and minimized stress
• Directional curved slots increase pad bite and improve air circulation
• Slots help vent gases, reduce brake fade, and prevent hydroplaning in wet weather
• Premium cast iron construction manufactured to OEM specifications
• Machine balanced for smooth, vibration-free operation
• Corrosion resistant ZRC coating provides a clean appearance and prevents rust and oxidation
• Up to 30% improvement in stopping performance compared to factory rotors

SP Performance rotors combine the advantages of both cross-drilled holes for superior cooling and directional slots to expel brake dust and gases. The chamfered drilling method reduces heat checking and warping while extending both rotor and pad life. Each rotor is machined and plated to order by SP Performance employees, ensuring consistent quality and precision fitment.
