The 570S is a pretty hardcore machine in stock guise, but the folks from McLaren Special Operations (MSO) improve on it with a number of offerings.

The latest one is called the “MSO Defined High Downforce Kit” and does exactly what the name says: it increases downforce, thus making the car more stable at high speeds. The kit consists of two main elements, a big, fixed rear wing made of carbon fiber, and underbody guide vanes.

McLaren’s in-house tuner says the wing works the airflow to generate additional downforce while the guide vanes located under the front of the vehicle filter the air that passes beneath the car to reduce drag. The vanes channel air away from the rear diffuser and force it to exit below the doors, thus creating a low-pressure zone at the front of the car to balance the increased downforce from the rear wing.

The High Downforce Kit is said to add an impressive 75 kg (165 lbs) of extra downforce. While that helps increase high-speed stability, it also “leaves the characteristically agile dynamics of the Sports Series firmly intact during lower speed driving,” according to MSO.

Finished in Gloss Visual Carbon Fiber, the wing also improves the aesthetics of the 570S and 570S Spider — it’s not available for the McLaren 570GT, though, most likely due to the latter’s different rear end design.

Each side features contrasting end plates with Silver Chromatic MSO branding and is supported by two pylons finished in High Gloss Black with Palladium Grey inserts, while it also incorporates the third brake light.
