Q: (Byron Young - The Daily Mirror) And you get both of them. They’re faster and better front wings and you get both of them. Mark doesn’t get one and you get the other.
SV: You are pretty smart if you know that they are faster and better. We try to keep this kind of thing to ourselves as much as we can, with the new parts, if they work or if they don’t but it looks like we have a leakage!
