Original under trays on Gen 1 cars are made from a weak fibre material and are prone to failure over time, whereas Gen 2 cars feature a plastic under tray but with a small single vent for the transfer case alone.
Our direct replacement aluminium under tray is a perfect fit that reuses all original mounting points and fixings whilst providing vastly improved cooling to the vital transmission components, as well as enhancing strength to the underside of the car.
Technical Data
As part of our expanding Toyota product range, AIRTEC Motorsport is proud to launch our direct replacement aluminium under tray for the Yaris GR Gen 1 and Gen 2 models including automatics.
The Issue
The original under tray on Gen 1 cars features no venting at all and is made from a weak fibre material construction which will be prone to failure over time. Gen 2 cars feature a plastic under tray but with a small single vent for the transfer case alone.
Construction
Our solution to creating a direct replacement under tray began with a full 3D scan of the vehicle’s underside to ensure a perfect fitment that reuses all original mounting points and fixings. Made in 2mm aluminium and finished in a high-quality black powder coat, our under tray offers an enhanced level of protection to the underside of the car but more importantly, the design has also been carefully considered to ensure improved cooling and air flow to the vital transmission components.
Cooling
Whilst the Gen 1 under trays feature no cooling at all, the Gen 2 under trays feature a basic duct for the transfer case at the rear, as clearly Toyota see this as an area that requires cooling. The AIRTEC Motorsport under tray therefore utilises a much larger scoop for the rear to force more air flow and offer better cooling. It also features a built in gearbox cooling duct, together with a venting section behind it to create air flow to and from the transmission and reduce temperatures. The comprehensive design also features rear ventilation to allow heat to exit the under tray together with side vents to further improve air flow.
Conclusion
A simple yet effective upgrade that offers improved strength, durability and cooling effectiveness.
PLEASE NOTE: The under tray uses existing mounting points – but it is essential the fixings you use to secure it are of good quality. The original Toyota fittings should only be reused if they’re in good condition. Worn, corroded or broken fixings should be replaced with new items from Toyota, 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.
