Jinnge's brake discs for sedans focus on lightweight design and noise reduction. Made from GG20 cast iron with a vermicular graphite structure, they are 10-15% lighter than conventional discs without compromising strength. The ventilated design features 36 radial fins, optimized for balanced airflow and reduced noise (≤68dB). A special anti-rust coating (zinc phosphate + electrophoretic paint) provides 500 hours of salt spray resistance. These discs are compatible with popular sedan models from brands like Toyota, Volkswagen, and Honda, with specific designs for front and rear axles, ensuring optimal braking performance in urban and highway driving conditions.
