PowerStop Front Evolution Drilled & Slotted Rotors - Pair

Fitment: Subaru Ascent (19-21)

Part #: JBR1789XPR

Overview

The PowerStop JBR1789XPR is a pair of high-performance front drilled and slotted rotors designed specifically for the Subaru Ascent from 2019 to 2021. These rotors are engineered to enhance your vehicle’s braking system by providing superior heat dissipation, improved cooling, and increased stopping power. Ideal for drivers seeking a reliable upgrade that combines durability with enhanced braking response, these rotors are perfect for both daily driving and demanding driving conditions. Their precision cross-drilled design helps maintain consistent brake performance, even during extended or aggressive use, while the slotted surface helps sweep away dust, gasses, and moisture for a cleaner brake pad contact and reduced brake fade. The zinc plating adds corrosion resistance, ensuring long-lasting performance and a clean appearance over time.

Key Features

Designed with performance and durability in mind, these rotors feature a zinc plating finish to resist rust and corrosion. The drilled holes and slots are precisely machined to optimize heat dissipation and airflow, helping to prevent brake fade during intense driving. The slotted design also aids in removing debris and moisture from the braking surface, maintaining consistent contact and response. Constructed from high-quality cast iron, these rotors are built to withstand extreme conditions while providing a noticeable upgrade over stock components. Their bolt-on installation makes them a straightforward upgrade for your vehicle’s braking system, offering improved cooling and enhanced braking feel without the need for additional modifications.

Construction & Design

These rotors are crafted from durable cast iron with a zinc plating coating that protects against corrosion. The cross-drilled holes are strategically placed to maximize heat dissipation, while the slots are designed to sweep away gasses and debris, maintaining optimal brake pad contact. The precision machining ensures a balanced, vibration-free operation for smooth braking performance.

Driving Feel & Feedback

The drilled and slotted design provides a more responsive and confident braking experience. Drivers will notice improved pedal feel and reduced brake fade during extended or aggressive braking, especially in high-temperature conditions. The enhanced cooling capabilities help maintain consistent braking performance, contributing to safer driving under demanding circumstances.

Installation & Fitment

These rotors are designed as direct bolt-on replacements for the OEM front rotors on the Subaru Ascent (2019-2021). Proper installation requires standard hand tools and should be performed following manufacturer guidelines to ensure optimal performance and safety.

What’s Included

The package includes a pair of front drilled and slotted rotors, ready for installation. Hardware and additional components are not included and should be transferred from the original rotors if necessary.
