Improving the GT500's dual-disc clutch to 5.8 standards was challenging, not only because of the 5.8's extra torque, but also due to its higher 7,000-rpm capability. New friction material forms a two-layer sandwich, with one layer optimized for wear and the other for burst strength. Furthermore, the material is less dense to keep inertial loads manageable so the clutch will function at high rpm. The four marcel springs in the center of each of the two discs were also redesigned for quicker response during clutch release. Here the front disc is propped up for a better view, while the rear disc's center is visible in the pressure plate assembly.
