F1TECH: McLaren modifies the floor and the front brakes with its Silverstone upgrades

McLaren Racing has arrived at the British Grand Prix with a focused development package aimed at improving both local aerodynamic efficiency and overall flow conditioning on its 2026 Formula 1 car.

Rather than a large visual overhaul, the Woking-based team has opted for two targeted upgrades that refine how air is managed at both the front of the car and under the floor, two of the most critical performance areas in modern Formula 1 design.

The first change is a revised front brake duct assembly, introduced with the goal of improving flow conditioning around the front corner of the car.

While brake ducts are primarily responsible for cooling, in current ground-effect regulations they also play a significant aerodynamic role. By reshaping this area, McLaren is aiming to better control the airflow that passes around the front wheel and into the car’s downstream surfaces.

The result is expected to be a more efficient airflow structure, which can translate into a small but meaningful increase in aerodynamic load and improved overall balance through corner entry.

The second upgrade focuses on the floor, where McLaren has revised the floor board and several elements of the floor “furniture” — the detailed aerodynamic structures that help guide and energise airflow beneath the car.

By refining these elements, McLaren is aiming to improve the quality of the airflow underneath the car, enhancing flow stability and increasing overall aerodynamic efficiency. This should help the car generate more consistent downforce while also improving how the floor responds across different speeds and ride heights.
