Dynamic Friction 930-63110A DFC Geomet Dimpled Slotted Brake Rotor

The Dynamic Friction Company (DFC) 930-63110A is a premium Geomet-coated dimpled and slotted brake rotor engineered for enhanced braking performance and long-term corrosion resistance. Geomet coating is a water-based, chrome-free inorganic zinc coating applied to the entire rotor — including the vanes and hat — providing superior rust protection compared to conventional e-coat or painted rotors.

The dimpled and slotted surface design serves a dual purpose: slots continuously clean and deglaze brake pad surfaces for consistent bite and fade resistance, while dimples help dissipate heat and gas buildup during heavy braking. Together, these features deliver improved stopping power, reduced brake fade, and a more responsive pedal feel.

Key Features:

• Geomet Coating: Full-rotor zinc-based coating resists corrosion and eliminates unsightly rust blooming common on bare rotors
• Dimpled & Slotted Design: Promotes pad deglazing, gas venting, and heat dissipation for consistent, fade-resistant braking
• Precision Machined: Manufactured to strict OEM tolerances for proper fitment, minimal runout, and vibration-free operation
• Balanced Construction: Each rotor is individually balanced to reduce brake noise, pedal pulsation, and steering wheel vibration
• Direct OEM Replacement: Bolt-on installation with no modifications required
• DFC Part Number: 930-63110A

DFC Geomet dimpled and slotted rotors are an excellent upgrade for drivers seeking improved braking performance and long-lasting corrosion protection over standard OEM rotors. Ideal for street performance, daily driving, and light track use.
