Basically Horner denied any adjustment were made at Parc ferme, but from what he said, It looked like the RB suspension can be adjusted without using any tool (he didn’t explicitly said that the RB car suspension can be adjusted without using any tool).
Btw, a couple of minutes ago I tried to visit f1fanatic and indeed my browser (firefox) throw a warning. I choose to ignore it and I believe it gave me another warning screen which I can choose something like “mark this sites as safe” (It wasn’t worded like that! but it essentially telling the “authority” that this site is safe). Whether or not it just a simple white list for my PC or it affects others I don’t know. But subsequent visit to f1fanatic, firefox didn’t gave me any warning.
