Japan Saturday quotes: Bridgestone

Hirohide Hamashima - Director of Bridgestone Motorsport Tyre Development: "It was good to have a dry qualifying session here at Fuji, compared to the wet and foggy conditions we saw here last season, and it was an exciting session too. We saw interesting differences between the Q2 and Q3 times from competitors, so I think tomorrow there will be a range of different strategies

"Today was interesting for Bridgestone as all of our range of tyres were used, with the wet and extreme wet tyres used this morning and the medium and soft compounds used this afternoon. This means teams have a lot of data when they look to the skies to consider their options for tomorrow's race. Rear tyre degradation will be at the forefront of drivers' minds and how they manage this will be the key point for a strong result.

"There is still some room for improvement from the track if we do not see any more rain. For those watching the race, how our green grooves disappear from the tyres as they are used will illustrate the differences between the cars, set-ups and drivers. The challenges of the Fuji track means the outer grooves are likely to wear first, as opposed to most circuits where it is the inner grooves which suffer more."
