| Williams Japanese GP Friday Practice |

Objectives P1 • Wet running and wet tyre compare • Aero systems checks Objectives P2 • Set-up tuning for the wet • Grid starts |
Nico Rosberg:
![]() "Today was just a matter of trying out the tyres in order to get an understanding of where the change over points are and how the inters and full wets are working, degradation-wise. What was clear was that I pretty much destroyed the wets when the track dried out. With the information from both cars, we now have a good understanding of what is going on."
Runs P1: Run 1 new wets (1
lap) install, run 2 scrubbed wets (4 laps) baseline, run 3 new inters (8
laps) mechanical set-up, run 4 scrubbed inters (7 laps) fuel system test |
Kazuki Nakajima:
![]() "Not a great day in terms of weather, but in terms of results it was ok. We didn’t get many laps in, but those we did get gave us a good platform for any potential wet weather running over the weekend. It looks positive, so hopefully we’ll be in the same position tomorrow for qualifying, but in the dry, preferably!"

Sam Michael Technical Director
Williams F1: "It
was a fairly uneventful day in terms of running the cars due to the
weather. We checked both full wet and intermediate tyres and the wet
set-up. Now we’ll prepare the cars for qualifying with new engines and
the race gearboxes. We’ll have to be conservative on the gear ratios
tonight due to no dry running at all." |
