DFC Front Drilled Hi-Carbon Alloy Geomet Coated Rotor Subaru STI 2018-2021 | 920-13041

Product Fitment:

2018-2021 Subaru STI

Upgrade your braking performance with the Dynamic Friction 920-13042 Hi-Carbon Alloy Drilled Brake Rotor. Engineered for both daily driving and performance applications, this rotor delivers improved heat dissipation, consistent stopping power, and long-lasting durability.

Manufactured using premium G3000/G11H18 high-carbon iron castings, this rotor is built for strength and stability under demanding conditions. The drilled design helps reduce heat buildup and brake fade, while maintaining reliable performance during aggressive driving.

Each rotor is precision mill-balanced to eliminate vibration and ensure smooth braking at any speed. A Geomet® anti-corrosion coating protects against rust and environmental wear, extending the life of the rotor and maintaining a clean appearance.

Finished with a fine-machined surface, this rotor promotes faster pad bed-in and improved braking efficiency right out of the box.
