The Zimmermann® Sports Brake Disc is a unique result of the experience of brake discs in series-production vehicles in connection with racing. The exceptional braking result is achieved by combining high-quality cast materials with a perforated braking surface. The permanent expulsion of brake dust and water through the drilled channels ensures outstanding braking performance in all weather conditions.
