Dynamite Friction 900-31108 Disc Brake Rotor - Front

Overview of Dynamite Friction DFC Hi-Carbon Alloy GEOMET Coated Rotor

The Dynamite Friction DFC Hi-Carbon Alloy GEOMET Coated Rotor (part number 900-31108) is engineered for precision braking performance on select BMW models. Designed as a vented disc brake rotor, it offers enhanced heat dissipation and durability for vehicles such as the BMW 328i xDrive and 435i Gran Coupe.

• Vented rotor design for improved cooling and reduced brake fade
• Nominal thickness of 30 mm with a discard thickness of 28.4 mm
• Outside diameter measures 340 mm, compatible with specific BMW models
• Five bolt holes with a diameter of 16.6 mm for secure mounting
• Height of 73.6 mm and inside diameter of 79 mm for precise fitment

Detailed Product Features and Specifications

This disc brake rotor features a vented construction that allows air to flow between the rotor surfaces, helping to maintain optimal operating temperatures during braking. The nominal thickness of 30 mm ensures structural integrity, while the discard thickness of 28.4 mm indicates the minimum safe thickness before replacement is necessary. The rotor’s 340 mm outside diameter and 79 mm inside diameter are designed to match the brake system specifications of various BMW models, including the 118i, 230i xDrive, and M240i xDrive. The five bolt holes, each with a diameter of 16.6 mm, provide a secure and stable attachment to the wheel hub. Additionally, the rotor height of 73.6 mm supports proper alignment within the braking assembly.

DFC Hi-Carbon Alloy GEOMET Coated Rotor Product Line

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line by Dynamite Friction incorporates a high-carbon alloy material combined with a GEOMET coating. This coating enhances corrosion resistance and extends rotor life by protecting against rust and environmental wear. The high-carbon alloy composition improves rotor strength and heat dissipation, contributing to consistent braking performance under demanding conditions. This product line is tailored for drivers seeking reliable and durable rotors compatible with a range of BMW vehicles.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 320i and 335i xDrive models
• Addresses brake fade caused by overheating during extended driving
• Resolves vibration or pulsation issues linked to rotor thickness below discard limits
• Prevents corrosion-related rotor damage with GEOMET coating
• Ensures proper fitment and braking performance on BMW 430i Gran Coupe and M135i

Installation Notes and Tips

When installing the Dynamite Friction 900-31108 rotor, verify that the rotor thickness is above the discard thickness of 28.4 mm. Ensure the five bolt holes align correctly with the vehicle’s hub assembly. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system performance. Proper torque specifications should be followed to secure the rotor without causing distortion.
