Stoptech Power Slot Brake Rotors

Fitment: Lexus GS/IS (06-15)

Part #: 126.44141SR

Overview

The Stoptech Power Slot F&R Slotted Brake Rotors are high-performance replacement rotors designed to enhance your vehicle’s braking response and durability. Crafted for Lexus GS and IS models from 2006 to 2015, these rotors are ideal for drivers seeking improved stopping power, heat dissipation, and consistent performance under demanding conditions. Whether you use your vehicle daily, tow heavy loads, or enjoy spirited driving, these rotors help support your braking system’s efficiency and reliability, contributing to safer and more confident driving experiences.

Key Features

Designed with performance in mind, these rotors feature a one-piece cast iron construction that ensures strength and longevity. The slotted design helps to evacuate brake dust, gases, and water from the rotor surface, maintaining optimal contact between the brake pad and rotor for consistent braking performance. Cryo treating options further enhance the rotor’s hardness and resistance to thermal fatigue, extending service life and maintaining braking feel over time. The slotted pattern not only improves braking response but also reduces brake fade during repeated or aggressive stops, making them suitable for a variety of driving styles.

Construction & Design

These rotors are made from high-quality cast iron, engineered to withstand high temperatures and heavy use. The slotted surface is precisely machined to ensure uniformity and effective debris removal, supporting consistent brake pad contact and heat management. The cryo treatment option involves controlled cooling processes that enhance the rotor’s structural integrity, helping to prevent warping and cracking under intense braking conditions.

Driving Feel & Feedback

The slotted design provides a more responsive and confident braking feel, especially during high-demand driving scenarios. Drivers will notice improved modulation and reduced brake fade, resulting in a more controlled and predictable stopping experience. The rotors help maintain consistent pedal feel, even after extended use or heavy braking.

Installation & Fitment

Installation requires standard brake service procedures; however, proper torque specifications and rotor bedding are recommended to maximize performance. Fitment should be verified against the vehicle’s specifications and the part number provided.

What’s Included

The package includes the front and rear slotted brake rotors, designed as direct replacements for your vehicle’s existing rotors, with hardware compatible for a straightforward installation.
