SP Performance S55-178-P Cross Drilled and Slotted Brake Rotor with ZRC Coating

The SP Performance S55-178-P is a high-performance cross drilled and slotted brake rotor designed to deliver superior stopping power and heat dissipation. Combining both cross-drilled holes and directional curved slots, this rotor provides exceptional cooling while effectively expelling brake dust and gases from the braking surface.

Key Features:

• Cross drilled holes machined with exclusive sinusoid curve chamfer to eliminate sharp edges and reduce stress cracking
• Directional curved slots increase brake pad bite and improve air circulation for enhanced cooling
• Slots help vent gases, reduce brake fade, and prevent hydroplaning in wet conditions
• Corrosion-resistant ZRC coating provides long-lasting protection against rust and oxidation
• Machine balanced and disc ground to meet or exceed OEM specifications
• Direct replacement for stock rotors with no brake system modifications required
• Manufactured in the USA using premium quality castings with CAD design and CNC machining

The advanced chamfered drilling method eliminates sharp edges that can lead to heat checking and cracking, while the combination of holes and slots keeps the braking surface clean for optimal pad-to-rotor contact. SP Performance backs this rotor with a lifetime warranty against defects in workmanship and guarantees it will not crack for the life of the rotor when properly installed and maintained.
