Product Description

The EBC S9KF1703 Stage 9 Front Brake Kit is engineered for Mustang owners seeking a substantial upgrade in braking performance without compromising everyday drivability. By combining EBC's renowned Yellowstuff high-friction brake pads with USR fine-slotted sport rotors, this kit delivers stronger stopping power, improved pedal response, and enhanced resistance to brake fade during spirited driving.

The Yellowstuff compound is formulated from advanced aramid fibers and is designed to perform effectively across a broad temperature range. Whether used for aggressive street driving, canyon runs, autocross events, or occasional track sessions, the pads maintain strong friction characteristics while remaining suitable for daily use. The USR rotors feature precision-machined slots that continually refresh the pad surface and aid in the evacuation of heat, dust, and gases generated during braking.

EBC's corrosion-resistant Geomet coating helps preserve rotor appearance and durability, while the complete matched-kit design ensures component compatibility and balanced braking performance. As a direct-fit solution for compatible S550 Mustang applications equipped with the 352mm front brake package, the S9KF1703 provides an effective performance upgrade for enthusiasts looking for increased confidence behind the wheel.
