SP Performance S54-121-R SP Performance Double Drilled & Slotted Performance Rotor Set, Red Zinc Coated

The SP Performance S54-121-R Front Double Drilled and Slotted Brake Rotors deliver enhanced stopping power and superior cooling for demanding driving conditions. These performance brake rotors combine the benefits of cross-drilled holes and directional curved slots to maximize braking efficiency while maintaining structural integrity.

Key Features:

• Double drilled and slotted design provides optimum cooling and debris removal
• Exclusive Sinusoid Curve Chamfer eliminates sharp edges on drilled holes to prevent cracking and heat checking
• Directional curved slots increase pad bite and expel brake dust and gasses
• ZRC corrosion-resistant coating prevents rust and oxidation while providing a clean appearance
• Manufactured to OEM specifications with machine balancing for vibration-free operation
• Made in the USA using high-quality castings that exceed OEM standards
• 331mm diameter, 8-lug front rotor configuration

The advanced drilling method features chamfered holes that promote maximum air circulation while reducing stress concentrations that can lead to rotor failure. The curved slot pattern helps maintain consistent brake pad contact, reduces brake fade in high-temperature situations, and eliminates hydroplaning by channeling water away from braking surfaces. Each rotor is CNC-machined for precision fitment and double disc ground to ensure proper installation without modifications.
