The R1 Concepts drilled black brake rotor for the front right of 2009–2011 Cadillac STS is a wheel-position-specific replacement. The drilled surface assists in heat dispersion and provides a distinct look compared with non-drilled rotors, while the black finish keeps a subdued, factory-coordinated appearance. Select this rotor for the front right position when servicing STS models from 2009 through 2011.
