Belgium preview quotes: Bridgestone

Kees van de Grint - Head of Track Engineering Operations: "Spa is extremely challenging as it is a very fast track. To the contrary of some other fast tracks, where the downforce loads placed on the tyres are lower because of low drag set-ups on the cars, here a higher level of downforce is applied. This means the tyres are placed under gruelling conditions with high speeds and high loads for almost the entire lap."

Q. How difficult is making the correct tyre choice in a wet weather race?

KvdG: "Wet conditions can change so quickly that it is very difficult to make the right call. We always calculate and present to the teams the conditions when you should change from the dry tyre to the wet tyre and then to the extreme wet, and vice versa, but in race conditions it is not so straightforward. We can control many things, and we have many computers, but the one thing that we can't control is nature."
