Airtec Motorsport Aluminium Under Tray for Ford Ford Focus Mk4 ST
Part of Airtec's expanding Ford range, this aluminium under tray is a direct replacement for the Ford Focus ST Mk4, addressing the fibre-material factory tray's tendency to fail over time.
Built from a full 3D scan of the car's underside for an exact fit, it reuses all original fixings and mounting points. The design is flatter and smoother than standard, adding 20mm of extra ground clearance that particularly benefits lowered cars, while still using larger air ducting than the original — including a bigger duct designed to let Airtec's secondary intercooler work more effectively — with rear venting to further improve cooling airflow.
