EBC USR slotted front rotor set for 2004–2008 Audi S4 4.2 applications. The USR series uses progressively angled slots to pull cool air through the disc, helping brakes run cooler while reducing air noise. British-made grey iron construction is precision machined and vented; this vented, 345mm diameter front rotor with 5-bolt pattern and 30mm thickness suits matching high-friction pad pairings.
