As part of our expanding Ford product range, AIRTEC Motorsport is proud to launch our aluminium under tray for the Focus ST Mk4.

Our solution to creating a direct replacement under tray in 2mm aluminium began with a full 3D scan of the vehicle's underside to ensure a perfect fitment. As a result, it reuses all original fixings and mounting points, offering improved strength and protection for the underside of the car.

We then designed the under tray to be flatter with a smoother surface to help air flow under the car whilst offering 20mm more ground clearance in comparison to the original, which hugely benefits lowered vehicles. Despite the flatter profile, the air ducting is larger to help improve cooling and also features a much bigger duct designed to allow ourAIRTEC Motorsport secondary intercoolerto work much more effectively. The back of the undertray is also vented at the rear to further improve air flow and aid cooling.

Lastly, as the the original under tray is made from a fibre material construction which is prone to failure over time, our aluminium replacement offers increased strength.

Finished in a high-quality black powder coat finish, the under tray offers improved durability and cooling effectiveness.

PLEASE NOTE:The under tray uses existing mounting points and bolts, but it is essential the original plastic fittings the bolts screw into are in good condition. These should only be reused if they still support the bolt properly and you are able to tighten it firmly. If they are worn or broken and offer little to no resistance as you wind the bolt in, they should be replaced with new items from Ford, as failure to do so may cause the under tray to work loose.

What does an under tray do?
The under tray has three main purposes: to protect the underside of the vehicle from foreign objects flicking up and causing damage or accelerated wear. Secondly, to improve aerodynamics by creating a low pressure area as air accelerates past its smooth surface. This reduces drag, which works towards improving grip, handling as well as fuel efficiency.

Lastly, on performance models, the under tray often provides increased cooling by either venting cold air to, or extracting warm air from the engine bay. Therefore improving the strength, design, size and cooling effect can offer fantastic benefits.
