51757349700 Rear Cover | Structural & Aerodynamic Integration

Precision-engineered for the central underbody section of LCI 5 Series Gran Turismo models, the 51757349700 Rear Cover features impact-modified polypropylene with structural reinforcement ribs. The symmetrical airflow channels maintain balanced underbody pressure distribution, reducing wind noise by 19dB at 120km/h compared to previous designs. Precisely aligned mounting points ensure tool-free installation with factory-grade alignment.

Integrated drainage ports prevent water accumulation while maintaining aerodynamic efficiency. The textured surface finish resists stone chips and road debris abrasion. Compatible with both standard and M Sport exhaust configurations, the cover maintains 12.5cm ground clearance across all suspension settings. Engineered thermal expansion slots compensate for temperature fluctuations from -30°C to 130°C.
