Construction & Design

The PowerStop Evolution Drilled & Slotted Rotor is meticulously crafted from premium cast iron, ensuring strength and resistance to warping under high heat conditions. The rotor's drilled holes are strategically placed to maximize heat dissipation and reduce brake fade, while the slotted surface helps maintain consistent brake pad contact and improves overall braking efficiency. The vented design allows air to flow freely between the two rotor surfaces, further aiding in cooling during intense braking sessions.

Manufactured with precision machining, these rotors feature a smooth, flat surface that ensures optimal pad contact and minimal vibration. The drilled and slotted pattern not only enhances performance but also adds a distinctive, aggressive look to your vehicle's wheel assembly. The design is engineered for easy installation, matching the OEM specifications for a perfect fit without the need for modifications.

Performance & Sound

With the PowerStop JBR1377XL rotor, you can expect improved braking performance compared to standard OEM rotors. The drilled and slotted features help reduce heat buildup and brake fade, providing more consistent stopping power during spirited driving or heavy braking conditions. The design also aids in expelling brake dust and gases, resulting in cleaner wheels and quieter operation. While specific performance numbers are not provided, users typically experience enhanced pedal feel, shorter stopping distances, and increased confidence behind the wheel.
