So... Ferrari really saw a huge improvement in the performance of their car driven by Leclerc this past weekend, and I believe a lot of that is due to the upgrade they carried out with the new floor and front wing. But, Leclerc has already said that his car still has a weakness in straight line speed, which could possibly expose the team at the British GP at Silverstone.
From what I've been reading, this new Ferrari design was thought not only to increase the downforce but also to make the SF-23 more "soft" (I don't know how to explain it/what term to use).
Anyway... Initially it seems to me that the update gave the impression of having worked as expected, as Leclerc easily won the second position on Friday, half a tenth of pole Max Verstappen, while Carlos Sainz shone on Sunday, but I think Leclerc will need to remain cautious for the British GP, held at a high-downforce circuit like Silverstone, and could be a real test of the evolution of the Italian team.
