The StopTech Drilled Sport rotor is a one-piece replacement rotor specified for certain BMW models, featuring cross-drilled holes to aid heat and brake dust evacuation, reduce pad glazing and increase initial bite in wet or dry conditions. A black e-coating provides corrosion protection while advanced metallurgy improves crack resistance and reduces noise. It is engineered as a direct OE replacement where drilled rotors are supported.
