EBC Brakes S9 Yellowstuff Pads and USR Slotted Rotors Kit for 1990-1994 Mazda Miata (S9KF1668)

Fits 1990-1994 Mazda Miata (Base, LE, M Edition, and SE).

The EBC Brakes S9 Kit is a premium performance brake upgrade designed for street and track use, combining high-friction Yellowstuff pads with USR fine-slotted sport rotors. This matched component set provides a significant increase in stopping power while maintaining quiet operation on the road. By purchasing as a kit, you ensure component compatibility while reducing the total cost compared to buying pads and rotors separately.

The included Yellowstuff pads are GG-rated for high friction and feature EBC’s patented Brake-In coating for rapid pad seating. To ensure quiet performance and durability, the pads are fully shimmed, chamfered, and slotted. These are paired with USR series rotors, which utilize a fine-slotted pattern to vent gas and debris without the wind noise often associated with wider-slotted rotors. Both rotors are treated with a Geomet anti-rust coating to maintain a clean appearance and prevent corrosion on non-contact surfaces.
