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 1998 - 2004 Audi A3, 1998 - 2006 Volkswagen Golf, 1998 - 2011 Volkswagen Beetle, 1998 - 2015 Volkswagen Jetta, 2000 - 2006 Audi TT, 2001 - 2005 Seat Leon, 2001 - 2005 Seat Toledo, 2001 - 2009 Seat Cordoba, 2002 - 2012 Seat Ibiza, 2003 - 2017 Volkswagen Polo, 2007 - 2010 Volkswagen Golf City, 2008 - 2009 Volkswagen Jetta City, 2010 - 2011 Volkswagen Beetle Cabrio, 2011 - 2015 Volkswagen Clasico, 2011 - 2016 Audi A1
