Dynamic Friction 9004-20012 Hi-Carbon Alloy GEOMET Coated Disc Brake Rotor Set

The Dynamic Friction Company 9004-20012 is a Hi-Carbon Alloy GEOMET Coated disc brake rotor set engineered to deliver OE-quality braking performance with superior corrosion protection. Designed as a direct OE replacement, these plain (non-drilled, non-slotted) rotors are built to match original equipment specifications without requiring any modification during installation.

These rotors feature a high-carbon iron alloy formulation that incorporates Molybdenum, Chromium, and Carbon to enhance noise-dampening characteristics while providing greater strength, stability, and thermal conductivity compared to standard cast iron discs. Each rotor is engineered to match the OE vane configuration, including OE split-core technology for proper and maximum heat dissipation.

Key Features:

• GEOMET® Coating — Genuine GEOMET finish applied to the entire rotor surface for superior rust and corrosion protection over conventional zinc or paint coatings
• Ready to Install — GEOMET coating is processed dry and shipped dry; no cleaning or prep work required
• 100% Precision Mill-Balanced — Ensures smoother stopping and zero vibration at any speed
• Fine-Turned Finish (1.6 RMS) — Promotes faster rotor and pad break-in for improved initial braking performance
• High-Carbon Alloy Construction — Enhances noise dampening and provides increased durability over standard rotors
• OE Vane Configuration — Engineered to match factory vane design for maximum heat dissipation
• 100% Electronic Inspection — Each rotor is measured across 20+ attributes to confirm it meets OE specifications before leaving the facility
• Plain / Blank Style — Smooth rotor surface for OE-equivalent stopping performance

Dynamic Friction Company rotors are manufactured to stringent quality standards, making the 9004-20012 an excellent choice for everyday driving, performance street use, and demanding duty cycles where corrosion protection and braking consistency are critical.
