Korean GP practice quotes: Williams

Valtteri Bottas - 16th/18th: We did quite a few tests with the car today, both mechanical and aerodynamic. We still have quite a bit of work to do with the car balance as we are struggling with the front end, particularly in the mid-corner. We need to work on that, but the positive thing is that we seem to have made a step forward with the new front wing we tested on Pastor's car, so I look forward to trying that myself.

Xevi Pujolar, Chief Race Engineer: We had several tests across the two cars this morning including some small aero changes. Pastor ran a completely new front wing in FP1 which worked as expected and he therefore kept this through into FP2. Several mechanical set-up tests were also completed, with long runs for both drivers in FP2 to gather tyre information. Both drivers were happy with the car and tyres this morning but we didn't have the same pace this afternoon. We need to go through the data now to make sure we have the best configuration to improve both our qualifying and race pace this weekend.
