SP Performance S55-178 Cross Drilled Slotted Brake Rotor

The SP Performance S55-178 cross drilled and slotted brake rotor delivers exceptional stopping power with the combined benefits of both drilling and slotting technologies. This rotor gives the advantages of both drilled holes for cooling and slots to expel gasses and brake dust. By eliminating the sharp edges on the cross drilled holes, it greatly reduces the chance of cracking by moving the air and brake dust from the disc brake surface while reducing the surface temperature.

Key Features:

• Cross drilled holes are machined with an exclusive sinusoid curve chamfer, which promotes cooling and minimizes stress
• Directional curved slots help increase pad bite, improve air circulation and cooling
• Corrosion resistant finishes give a stunning clean look behind your wheels while preventing rust, corrosion and oxidation, available in Gray ZRC, Silver ZRC, or Black ZRC
• Manufactured in the USA - all rotors are machined and plated to order by SP Performance employees
• Made using the finest quality castings that exceed OEM specifications
• Machine balanced and disc ground
• Direct replacement for existing brake rotors with no brake system modifications required

The combined forces of the brake pad rubbing against the brake rotor surface creates gasses and extensive heat which can cause brake fade, reducing stopping power. The holes in the brake rotor surface provide optimum cooling, while the slots keep the brake rotor surface clean providing a premium brake pad to brake rotor contact. This design effectively reduces brake fade and stopping distances in both dry and wet weather conditions.
