After a tricky day of stop-start action, Mercedes-AMG Petronas Motorsport Technical Director James Allison is expecting to see the pace ramp up on Saturday.
"It was a scrappy day punctuated every few seconds by dozens and dozens of off-track frolics," said James. "The associated yellow flags interrupted the rhythm at a circuit where it is quite challenging to get temperature into the tyres, especially the fronts, and that as much as anything dictated your position on the leader board today.
"However, we have work to do overnight to make the car's handling sweeter, as both drivers were struggling to get temperature into the front tyres and, as a consequence, suffering with front locking. There is going to be a lot more lap time to come from all of the front runners as the track rubbers in and the drivers gain in confidence.
"It's already close at the front, so I expect that those who work well overnight, and keep a cool head tomorrow, will be rewarded in qualifying and the race."
