EBC GD Sport Rear Rotors

1997–1998 Audi A4 Quattro 1.8 Turbo

Part #: GD909

Overview

The EBC GD Sport Rear Rotors are designed to enhance your vehicle's braking performance while adding a sleek, aggressive look to your Audi A4 Quattro. Crafted with both style and functionality in mind, these rotors are ideal for daily drivers who seek improved cooling, reduced brake fade, and a distinctive appearance. Whether you're commuting, enjoying spirited driving, or tackling occasional sport driving, these rotors provide a reliable upgrade over stock components.

Manufactured in the U.K., the GD Sport Rotors feature a combination of advanced slotting and dimple drilling techniques that work together to optimize heat dissipation and minimize stress cracks. The wide aperture slots allow for increased airflow, helping to keep brake temperatures low during demanding driving conditions. The dimple drilling not only enhances cooling efficiency but also reduces the risk of stress fractures, ensuring durability and longevity under various driving scenarios.

Key Features

The EBC GD Sport Rotors incorporate several innovative design elements that set them apart from standard brake rotors:

• Wide Aperture Slots: These slots improve heat dissipation and help prevent brake fade during extended or aggressive braking, maintaining consistent stopping power.
• Dimple Drilling: Strategically placed dimples increase surface area for cooling and reduce stress concentrations, which helps prevent cracks and extends rotor lifespan.
• Thermic Black Finish: The sleek black e-coating not only provides a stylish appearance but also offers excellent corrosion resistance, protecting against road salts and environmental elements.
• High-Quality Construction: Made from durable cast iron, these rotors are engineered for reliable performance and long-lasting durability.
• Made in the U.K.: Ensuring strict quality standards and craftsmanship for a premium product.
• Enhanced Cooling: The combination of slots and drilled holes promotes airflow, reducing operating temperatures and improving overall braking efficiency.
• Sporty Aesthetic: The black finish and slot/dimple pattern give your vehicle a performance-oriented look that complements any sporty or upgraded brake setup.

Construction & Design

The EBC GD Sport Rotors are precision-engineered with a focus on durability and performance. The rotors feature a one-piece cast iron construction, ensuring strength and resistance to warping. The wide aperture slots are machined into the rotor surface, providing increased airflow and heat extraction, which is crucial during high-demand driving. The dimple drilling is carefully placed to balance stress distribution and enhance cooling efficiency without compromising structural integrity.

The thermic black finish is applied through a high-temperature coating process that not only enhances the visual appeal but also offers excellent corrosion resistance, making these rotors suitable for all weather conditions. The combination of slotting and drilling techniques helps maintain consistent brake pedal feel and reduces brake fade, giving you confidence in both daily driving and spirited stops.
