Silver Arrows Trackside Engineering Director Andrew Shovlin was pleased with a well worthy day of Friday running, as the team worked on plans for 2018 as well as long-running in the warm conditions.
"We had quite a big programme this morning looking at some development items for 2018," said Andrew. "We had been putting off that work while we were still fighting for the championships, so it was very good to get that done.
"We have collected a lot of good data from those tests which will all feed into the development programme for the W09.
"The weather forecast looked like we might lose some running with the rain today but it was great that it stayed dry. It was really good to get some long run work done in the hot conditions both in FP1 and FP2 as it looks like we will have similar track conditions on Sunday.
"Overall, the cars are working well but it's been tricky today in the windy conditions and both drivers struggled to put their lap together on the super-softs.
"There are a few areas that we need to work to improve the car but it's been a solid start to the weekend and we're looking forward to a good fight with the Red Bulls and Ferraris."
