Our World Championship winning R-Line off-road race brake systems have proven themselves over a period of more than a decade in race conditions ranging from the scorching deserts of South America, the Middle East and Africa to the snow-covered forests of Northern Russia, to the fast gravel tracks of Mongolia in the hands of the world’s best off-road race car drivers. Our D-Line high performance disc and pad kits were designed by the same team that designed our renowned R-Line off-road race systems and they are manufactured on the same equipment, in the same factory. All design features (such as slot patterns, disc coatings and max temp recording systems), as well as the proprietary cast-iron alloys from which the discs are cast, have been directly developed through our extensive involvement at the highest levels of international off-road racing.
