Part #: DBA42957XS

Overview

The DBA 4000 Series Rear Drilled & Slotted Rotor is designed to enhance your vehicle’s braking performance and aesthetic appeal. Crafted for drivers seeking improved heat dissipation, reduced brake fade, and a sportier look, this rotor is suitable for Mazda 3 (04-05) and MazdaSpeed3 (06+) models. Its drilled and slotted design helps to manage heat and gases generated during braking, providing consistent stopping power and increased durability under demanding driving conditions. Whether you’re upgrading for daily driving or spirited performance, this rotor offers a reliable solution to support your vehicle’s braking system.

Key Features

This rotor features a high-quality construction tailored for performance and longevity. Its design incorporates precision-drilled holes and slots that facilitate heat dissipation and debris removal, helping to maintain optimal brake pad contact. Made from durable cast iron, it ensures resistance to warping and cracking. The slotted surface improves pad grip and reduces brake dust buildup, contributing to cleaner wheels and better braking response. The rotor’s finish is engineered for corrosion resistance, ensuring long-lasting performance even in harsh environments.

Construction & Design

The rotor’s construction emphasizes structural integrity with a cast iron core that withstands high temperatures and stress. The drilled holes are strategically placed to maximize airflow and cooling, while the slots are machined for precise fitment and consistent performance. The design aims to deliver a balance of strength, heat management, and aesthetic appeal, making it an ideal upgrade for enthusiasts and daily drivers alike.

Installation & Fitment

Installation should be performed by qualified technicians familiar with brake system upgrades. Proper measurement and verification of your existing brake discs are recommended to ensure compatibility, as fitment may vary depending on specific vehicle configurations. This rotor is designed as a direct replacement for the rear brake system on compatible Mazda models, but fitment details should be confirmed with your vehicle’s specifications.

What’s Included

The package includes one drilled and slotted rotor, ready for installation. Hardware or additional components are not included and should be sourced separately if required for your specific vehicle setup.

Ideal For

This rotor is ideal for drivers seeking improved braking performance, enhanced heat dissipation, and a sportier appearance. It is suitable for daily driving, spirited street use, and track days where reliable braking is essential.
