Q: We’ve heard quite a bit about spare parts from McLaren over the last couple of days, in fact the last couple of races. Have you got everything that Lewis has got now?

HK: In fact I would have everything if I wanted to take them, but because the parts arrived a bit late, the factory was just not able to push any more. Everybody has been stretched over the maximum in fact, to get all the pieces, so it was always a plan that Lewis would run them on Friday and I would get them perhaps for the Friday afternoon. But because everything was delayed and we had a very good balance yesterday, we decided not to run the new parts because you never know, you might lose confidence on Saturday morning which you really don’t want to do. So in fact it was our decision not to run them but I think I would have had them and the team would have given equal opportunity for both of us, so no problems on that side.

Even if it causes a minuscule 0.1% increase in performance, on a 100 second Valencia track, it transforms into an advantage of a tenth, which in formula one is significant.

Interesting that Kovalainen chose not to use some of the new aero parts, it reminds me of a race last year (can’t remember where of the top of my head) where Massa was using the shark fin engine cover but Raikkonen wasn’t purely out of choice rather than availability of parts.
