Stoptech D&S Rear Vented Cast Iron Rotor

Part #: 127.40042R

Overview

The Stoptech D&S 259.7mm Rear Vented Cast Iron Rotor is a high-performance brake component designed to enhance stopping power and durability for your vehicle. Crafted for enthusiasts who demand reliable braking under various driving conditions, this rotor combines advanced engineering with proven materials to deliver consistent performance. Whether you're daily driving, hauling, towing, or engaging in spirited driving or racing, this rotor helps support your vehicle's braking system with improved response and heat management. Its vented design promotes efficient cooling, reducing brake fade and maintaining optimal braking performance during demanding situations.

Key Features

This rotor features a one-piece construction made from high-quality cast iron, ensuring strength and longevity. The slotted pattern helps improve brake pad bite and debris removal, enhancing overall braking efficiency. Designed with a vented style, it provides superior heat dissipation, which is critical for maintaining consistent braking performance during extended use. The inclusion of cryo treating options further enhances the rotor’s hardness and resistance to warping, extending its service life and maintaining optimal performance over time. Its slotted and vented design not only improves braking response but also helps reduce brake dust and noise, contributing to a cleaner and quieter braking experience.

Construction & Design

The rotor’s cast iron construction is engineered for durability and heat resistance. The vented design features precisely machined slots that facilitate airflow and heat dissipation, helping to prevent overheating during aggressive driving or heavy-duty use. The cryo treating process, if selected, involves controlled cooling to improve the material’s structural integrity and wear resistance, ensuring the rotor maintains its performance characteristics over many miles.

Driving Feel & Feedback

This rotor is designed to provide a responsive and consistent braking feel, with improved pad engagement and reduced fade. The slotted surface helps optimize brake pad contact, resulting in more precise modulation and confidence during braking. Its durable construction ensures reliable feedback and performance, whether on daily commutes or track days.

Installation & Fitment

Installation should be performed by a qualified technician familiar with brake system upgrades. Proper torque and bedding procedures are recommended to maximize rotor lifespan and braking performance. Verify fitment against your vehicle’s specifications to ensure compatibility.

What’s Included

This product includes a single rear vented cast iron rotor designed for the specified vehicle applications. Hardware and additional components are not included and may need to be sourced separately.
