Setup, Compatibility & Care
Before installation, use a caliper to confirm your current disc diameter is 315 mm and thickness is 28 mm, as variations in Porsche braking packages can exist. The disc features a 130 mm bolt hole circle diameter and a 98 mm centering diameter. Always ensure the wheel hub surface is cleaned of rust and corrosion using a wire brush before mounting the new disc to prevent runout. After installation, perform a proper brake bedding-in procedure to ensure the pad and disc mate perfectly, extending the service life of both components. Always replace brake discs in axle sets (both left and right) to maintain balanced braking performance.
