Each Stroll and Alonso had hit the obstacles within the moist qualifying session, damaging the Suzuka-concept specification flooring the workforce had meant to run for the Interlagos occasion.
With no spares of that specification obtainable, Aston Martin needed to revert to a earlier ground model – which was the one it first launched on the Hungarian GP.
Usually groups can not change specs between qualifying and the race, as that could be a breach of parc ferme laws and mandates a pit lane begin.
Nonetheless, issues are totally different on a dash race weekend when allowances are made if there’s a scarcity of spare elements.

“Following each automotive’s accidents in qualifying, we needed to change a number of parts with a unique specification attributable to availabilities on the finish of a triple header. That is allowed by the Dash Occasion laws, and also you declare your shortages and substitute choices to the FIA earlier than the occasion.
