Q&A with Hirohide Hamashima - Bridgestone Director of Motorsport Tyre Development: Today was all about track improvement. The surface started very dirty, as we would expect so we heard the usual comments about lack of grip. We saw quite a bit of rear lateral graining which comes from the traction and braking demands on this circuit. We also saw some front lateral graining on some cars too. This is unusual, but comes from the heavy braking on the initially dirty surface."
"We would expect the super soft to be the superior tyre for lap time, but the soft to be the superior tyre for consistency and therefore the favoured race tyre. The amount of circuit improvement over the weekend will be the key to the race. As the circuit improves, so car balance will change. The team that predicts the track improvement correctly for the race will be best placed to refine their car setup to suit. Even though it was very hot here, the track layout does not put as much force through the tyres as at other circuits so we do not predict problems with tyres overheating."
