Dynamic Friction 4612-18079 GeoSpec Coated Slotted Disc Brake Rotors

The Dynamic Friction Company (DFC) 4612-18079 GeoSpec Coated Slotted Brake Rotors deliver a compelling blend of performance, corrosion resistance, and OE-quality fitment. Engineered with precision-machined slotted surfaces, these rotors are built for drivers who demand improved stopping confidence on the street without sacrificing long-term durability.

GeoSpec Coating:

These rotors feature DFC's proprietary GeoSpec patented coating, which forms a durable, attractive silver-gray finish that provides superior corrosion protection compared to conventional paint or zinc coatings. The GeoSpec finish is processed dry, shipped dry, and ready to install—no prep work required. During break-in, the coating on the friction surface is safely swept away by the brake pads with no harmful effects.

Slotted Rotor Design:

The precision-cut slots on the rotor surface continuously clear brake dust, gas, and road debris from between the pad and rotor face, preventing pad glazing and maintaining consistent bite. The slotted design also enhances pad grip to reduce stopping distances, especially in wet conditions.

Key Features:

• GeoSpec patented coating for superior corrosion resistance over zinc or conventional paint
• Premium G3000/G11H18 iron casting for strength, stability, and long-term durability
• CNC-machined to the tightest tolerances for precise OE-spec fitment
• 100% precision mill-balanced for smooth, vibration-free stops at any speed
• OE vane configuration ensures proper and maximum heat dissipation
• Non-directional surface finish promotes faster break-in and smoother, quieter stops
• Slotted design removes brake debris and prevents pad glazing
• Designed to meet the same form, fit, and function as OEM brake rotors
• Direct-fit replacement — no modification required

Each rotor passes a 100% electronic inspection station measuring over 20 critical attributes to confirm OE specification compliance before leaving the facility. The DFC 4612-18079 is an ideal upgrade for daily drivers seeking improved braking performance and lasting corrosion protection.
