AIRTEC Motorsport Aluminium Under Tray for Ford Fiesta ST Mk8

Technical Data

As part of our expanding Ford product range, AIRTEC Motorsport is proud to launch our aluminium under tray upgrade for the Fiesta Mk8 including ST.

The original under tray on these cars is notoriously weak due to the fibre material construction and as a result are prone to failure over time.

Our solution to creating a direct replacement under tray in aluminium began with a full 3D scan of the vehicle’s underside to ensure a perfect fitment. As a result, it reuses all original mounting points, as well two additional fittings using Rivnuts to existing holes in the front subframe to ensure strength and protect the underside of the car.

The design itself spans across the entire front end to help improve aero dynamics whilst the large centre scoop directs air up into the engine bay, helping to maintain under bonnet temperatures at speed. The second scoop is for the gearbox to help maintain transmission temperatures on track and road.

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. 

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.  

Features:

• Direct fit for designed specifically for the Fiesta Mk8 including ST
• Created from 3D scan and CAD software for perfect fitment
• Made from high-quality 2mm aluminium for increased strength
• Protects underside of the car and improves aero dynamics
• Ducting to help cool engine bay and transmission temperatures
• Comes in a durable black powder coat finish
• All fittings included, as well as a detailed installation guide

Please note: due to box sizes additional shipping costs may occur for international and EU customers.
