SP Performance S54-129 SP Performance Double Drilled & Slotted Performance Rotor Set, Gray Zinc Coated

The SP Performance S54-129 is a high-performance double drilled and slotted brake rotor designed to deliver superior stopping power and heat dissipation. This rotor combines the benefits of cross-drilled holes and directional curved slots to provide optimal braking performance for both street and performance driving applications.

Key Features:

• Cross-drilled holes machined with exclusive sinusoid curve chamfer for enhanced cooling and reduced stress
• Directional curved slots increase pad bite and improve air circulation while venting gases
• Manufactured in the USA to OEM specifications with precision machine balancing
• Available with corrosion-resistant ZRC coating in Gray, Silver, or Black finish options
• Cast iron construction designed using CAD software and produced on CNC machines
• Up to 30% improvement in stopping performance compared to stock rotors

SP Performance rotors feature a proprietary drilling method that eliminates sharp edges, reducing the possibility of heat checking and cracking while extending both rotor and pad life. The combination of drilled holes and slots works together to prevent brake fade, reduce hydroplaning in wet conditions, and maintain consistent performance under demanding conditions. Each rotor is backed by a lifetime warranty against defects in workmanship and cracking.
