Tofo17 won Mexico's D2 race from third for Williams, with team-mate Webbah87 climbing from fifth to third. Sirspinsal0t split the pair in second for Haas.
The two-car podium moved Williams into the D2 constructors' lead on 141 points, 26 ahead of Ferrari. Mexico changed the team order through both victory and depth.
P1 and P3 overturn the team table
Tofo gained two positions and Webbah87 gained two. Their parallel movement placed 1st and 3rd in Williams colours, enough to make the constructor change visible in the result itself.
The drivers' championship told a different story. Aban-96- remained first on 71, six ahead of LimitlessDraco3, while neither appeared in the recorded Mexico top three.
Williams wins the weekend and the wider argument
A constructor lead built by two scoring cars is more robust than a headline attached to one winner. Mexico gave Williams both: Tofo's victory and Webbah87's supporting podium.
Silverstone would begin with Williams no longer chasing Ferrari in D2. The 26-point advantage was the concrete reward for turning two mid-grid starts into two top-three finishes.
