Technical Data
As part of our expanding Ford product range, AIRTEC Motorsport is proud to launch our direct replacement aluminium undertray for the Mk3 Focus RS.
The original undertray on this car 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 undertray 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 three additional fittings on the front edge, and is nut and bolted both sides to ensure absolute security.
Unlike any other replacement undertray on the market, our design features no step, which is better suited to lowered cars. The cooling ducts are also larger in size to increase air flow passing over the gearbox and transfer case, which helps to reduce transmission operating temperatures and the sides pieces are larger to create a seal against the arch liners.
Finished in a high-quality black powder coat finish, the undertray offers improved strength, durability and cooling effectiveness.
PLEASE NOTE: The undertray 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 undertray to work loose.
The Ford part number for the plastic undertray fittings are as follows:
- W702438-S300
Features:
- Direct replacement for original Focus RS Mk3 undertray
- Created from 3D scan and CAD software for perfect fitment
- Made from high-quality aluminium for increased strength
- Uses original mounting points – no cutting or drilling required
- Additional mounting points for absolute security
- Improved transmission cooling due to larger ducting
- Comes in a durable black powder coat finish
