SP Performance S55-148-R Double Drilled Slotted Brake Rotor

The SP Performance S55-148-R is a high-performance double drilled and slotted brake rotor designed to deliver superior stopping power and enhanced braking performance. This rotor combines the advantages of both cross-drilled holes and directional curved slots to optimize cooling, reduce brake fade, and improve overall braking efficiency.

Key Features:

• Double Drilled Design: Features cross-drilled holes machined with SP Performance's exclusive sinusoid curve chamfer, which promotes cooling and minimizes stress while eliminating sharp edges that can cause cracking
• Directional Curved Slots: Strategically machined slots increase brake pad bite, improve air circulation, and help vent gases to reduce brake fade and prevent hydroplaning in wet weather conditions
• Corrosion Resistant Finish: Protected with SP Performance's ZRC (Zinc Rich Coating) finish available in gray, silver, or black to prevent rust, corrosion, and oxidation while providing a clean appearance behind your wheels
• Premium Construction: Manufactured from high-quality rotor blanks that meet or exceed OEM specifications, machine balanced and disc ground for vibration-free performance
• Made in USA: All rotors are machined and plated to order by SP Performance employees for consistent quality control
• Direct Bolt-On Installation: Engineered as a direct replacement for factory rotors with no brake system modifications required

The combination of cross-drilled holes and slots works together to provide optimal cooling while keeping the brake rotor surface clean for premium brake pad to rotor contact. The holes maximize air circulation and dissipate heat, while the slots expel brake dust and gases away from the braking surface. This dual-action design helps eliminate brake fade, reduces stopping distances, and maintains consistent braking performance even under heavy use. SP Performance rotors are backed by a lifetime warranty against cracking and defects in workmanship.
