Construction & Design

The PowerStop SC4065 rotors are constructed from premium cast iron, ensuring strength and durability under demanding conditions. The vented design promotes efficient heat dissipation, reducing the risk of brake fade during spirited driving or heavy braking. The slotted surface helps remove brake dust, water, and debris from the pad surface, maintaining optimal contact and braking efficiency.

The semi-coated finish on the rotors provides excellent corrosion resistance, especially in harsh weather conditions, helping your vehicle maintain a clean appearance and reliable performance over time. The precision machining process ensures a smooth, balanced rotor surface, minimizing vibrations and noise for a comfortable driving experience.

Performance & Sound

These rotors are designed to improve your vehicle's braking response and overall stopping power. The vented and slotted design helps manage heat effectively, reducing brake fade during aggressive driving or stop-and-go traffic. While specific performance numbers are not provided, users typically experience shorter stopping distances, more consistent pedal feel, and reduced brake dust buildup. The design also helps keep brake components cooler, prolonging their lifespan and maintaining optimal performance.
