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 2005 - 2010 Volkswagen Bora, 2005 - 2010 Volkswagen Jetta, 2006 - 2009 Volkswagen Rabbit, 2006 - 2012 Seat Altea, 2008 - 2009 Audi A3, 2010 - 2013 Volkswagen Golf
