The StopTech Slotted Sport left-front rotor is a one-piece direct-replacement disc suited to Audi Allroad (2001–2006), A4 (2005–2009), A6 (1999–2004) and S4 (1999–2002) front applications. Precision slotting helps disperse heat and brake dust to prevent pad glazing and increase bite; black e-coating guards against corrosion while high-carbon metallurgy reduces pad squeal and improves crack resistance.
