AIRTEC Motorsport Aluminium Under Tray for Focus ST / RS Mk2

Technical Data

As part of our expanding Ford product range, AIRTEC Motorsport is proud to launch our aluminium under tray for the Focus Mk2 ST and RS.

Our solution to creating a replacement under tray 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, as well five additional fittings to ensure absolute security whilst offering improved strength and protection for the underside of the car.

Made from 2mm aluminium for increased strength in comparison to the plastic original, our replacement under tray features a series of enlarged ducts and vents to encourage air flow and cooling. The vents are also designed to direct air specifically towards the OEM oil modine and transmission, in comparison to the original, which just sent air aimlessly towards the engine bay. It’s coupled with a A more open rear section and the slots are elongated in comparison to the original to allow heat to escape more effectively, promoting better engine cooling. It has also been designed to work with our big boost pipe kit, which fits under the engine.

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.

• To secure the under tray’s additional fixings two existing holes in the subframe require enlarging. 

• As the clearance between the enlarged scoop and the sump is reduced, it is strongly advised that an uprated torque mount is installed if the original shows signs of wear/excess movement.

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.
