StopTech Drilled Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique cross-drilling aids with heat and brake dust dispersal; prevents glazing of the pads; adds bite and improves wet and dry braking performance. Built to last; the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation; better crack resistance and increased performance. Premium e-coated rotor with advanced metallurgy that greatly reduces pad squeal. Especially effective with higher friction, European style brake pad compounds. Drilled for increased bite, improved looks and better performance Premium e-coated rotor with advanced metallurgy that greatly reduces pad squeal; Especially effective with higher friction; European style brake pad compounds; Added Molybdenum and Chromium to resist rotor cracking 2006 - 2006 Lexus GS300, 2006 - 2007 Lexus GS430, 2006 - 2015 Lexus IS350, 2007 - 2011 Lexus GS350, 2007 - 2011 Lexus GS450h, 2008 - 2011 Lexus GS460, 2010 - 2015 Lexus IS250
