EBC USR slotted front rotors for 1991–1992 Audi 100 Quattro are British-made, precision-machined vented discs with narrow slots engineered to reduce air noise while improving brake cooling. The USR series promotes cooler running, decreased fade at speed and a smoother pad surface over time. Slotted rotors paired with matching high-friction pads can extend pad life and enhance braking consistency on premium sedans.
