Part #: 900-31170D

Overview

The DFC Hi-Carbon Alloy Geomet Coated Rotor is engineered specifically for the left rear position of the 2020 to 2026 Toyota GR Supra. Designed to meet the demands of both spirited street driving and occasional track use, this rotor offers enhanced durability and consistent braking performance. Featuring advanced materials and protective coatings, it is an ideal upgrade for enthusiasts seeking improved heat dissipation, reduced brake fade, and extended rotor life compared to standard OEM components.

Whether you are upgrading your braking system for better control or replacing worn factory rotors, this DFC rotor provides a reliable solution that maintains OEM fitment and performance standards.

Key Features

DFC’s Hi-Carbon Alloy Geomet Coated Rotor incorporates several key technologies to optimize braking efficiency and longevity:

• High-carbon alloy construction for improved thermal stability and reduced cracking
• Geomet coating to resist corrosion, rust, and environmental wear
• Precision-machined surface for consistent pad contact and smooth braking feel
• Designed specifically for the left rear position to ensure perfect fitment and balance
• Enhanced heat dissipation properties to minimize brake fade during aggressive driving
• Compatible with OEM brake pads and calipers for straightforward installation
• Durable finish that maintains appearance and performance over time

Construction & Design

This rotor is crafted from a high-carbon alloy that offers superior strength and heat resistance compared to standard cast iron rotors. The increased carbon content helps to reduce the risk of thermal cracking and warping under heavy braking conditions. Additionally, the rotor is treated with a Geomet coating, a specialized anti-corrosion layer that protects against rust and extends the rotor’s service life, especially in wet or humid environments.

The rotor’s surface is precision-machined to provide a smooth, flat contact area for brake pads, ensuring consistent braking performance and reducing noise and vibration. Its design maintains OEM specifications for thickness and diameter, guaranteeing compatibility with the Toyota GR Supra’s braking system without requiring modifications.

Installation & Fitment

The DFC Hi-Carbon Alloy Geomet Coated Rotor is a direct replacement for the left rear rotor on 2020–2026 Toyota GR Supra models. Installation is straightforward and can be completed using standard brake service tools. No modifications to the vehicle’s braking system are necessary, and the rotor fits seamlessly with existing calipers and pads.

For optimal performance and safety, it is recommended to replace rotors in pairs and to inspect brake pads and hardware during installation. Professional installation is advised if you are not experienced with brake maintenance.

What's Included
