SP Performance S55-080-R Cross-Drilled & Slotted Front Brake Rotor

The SP Performance S55-080-R is a cross-drilled and slotted vented front brake rotor engineered for improved braking performance over stock rotors. Manufactured in the USA, this rotor is machined and plated to order by SP Performance employees using premium-grade castings that meet or exceed OEM specifications.

SP Performance's proprietary sinusoid curved chamfer drilling method eliminates sharp edges on every cross-drilled hole, promoting airflow and cooling while significantly reducing the risk of heat checking, stress cracking, and warping. The directional curved slots work in tandem with the drilled holes to increase brake pad bite, expel gases and brake dust from the rotor surface, reduce brake fade, and improve wet-weather stopping performance by preventing brake hydroplaning.

Key Features:

• Cross-Drilled Holes — Machined with an exclusive sinusoid curve chamfer for maximum air circulation with no sharp edges, reducing heat checking and extending rotor and pad life
• Directional Curved Slots — Increase pad bite, improve air circulation, vent gases, reduce brake fade, and minimize stopping distances in wet conditions
• Corrosion-Resistant ZRC Coating — Available in Gray ZRC, Silver ZRC, or Black ZRC for a clean appearance and lasting protection against rust and oxidation
• CAD-Designed & CNC-Machined — Designed with CAD software and produced on CNC machines for consistent tolerances and reliable performance
• OEM-Spec Balanced — Machine balanced and disc ground to OEM specifications for a direct, no-modification replacement fit
• Made in the USA — Machined and plated to order by SP Performance employees

SP Performance rotors are warranted to be free of defects in workmanship and guaranteed not to crack for the life of the rotor (as determined by minimum thickness). A proper break-in procedure must be followed after installation to ensure optimal brake performance and coating cure.
