The rain arrived ahead of Free Practice Three, but the track dried out for the start of qualifying.
Sebastian crashed in FP3 and, while his mechanics fixed his car, he was unable to make it out of the first part of qualifying. Lance was able to make it as far as Q2.
Lance's day started with some Wet tyre running in FP3. Across eight laps, he put in a best time of 1.45.789.
He then switched to the Intermediate tyre and completed nine laps and improved to a time of 1.45.638 to finish in 15th in the session.
With the track dry for qualifying, Lance took to the track on the Soft tyre.
His best effort on his first run was a 1.20.240, before improving to a 1.19.205 on his second set to squeeze into Q2 in 15th position.
In Q2, Lance once again did two runs on fresh Soft tyres, posting a 1.19.161 on his first run before improving to a 1.19.137.
However, this was only good enough for 14th position and he did not graduate into the final part of qualifying.
"To qualify 14th was not what we really wanted today. Yesterday we looked more competitive, but the conditions were very different today and we just generally struggled for grip.
"We will have to look at the data to analyse why things panned out the way they did today.
"We have been performing better on race day, but it is tricky to overtake here – so it will be tough to make progress in the race, but there might be some interesting weather tomorrow which can go in our favour."
Sebastian started FP3 running on the Wet tyre when the conditions were at their worst. He completed eight laps on the tyres and put in a best time of 1.44.178 during an eight-lap run.
He switched to the Intermediate tyre as the standing water started to clear. Despite that, the conditions were still tricky and Sebastian did not improve his time on the tyres.
Unfortunately, he lost control of the car at Turn 10 after running across a damp patch and hit the barriers, ending his session after 14 laps in total.
Despite the damage to the car, he was able to take to the track in qualifying thanks to a great effort from the team, including Sebastian himself who assisted the mechanics with the repairs.
However, his best effort across his two runs on the Soft tyre was a 1.19.273, which was less than a tenth off a place in Q2. He lines up 18th for Sunday's race.
"The off this morning in FP3 was a shame – obviously, it was my mistake, but I wasn't pushing too hard when it happened. The track improved quite a bit throughout Q1.
"I thought my first lap was good, but then I could only do one cool-lap, so the tyres were still a bit too hot for my final lap. It doesn't leave us in a good place for tomorrow.
"Getting the car repaired for qualifying with just minutes to spare makes failing to get out of Q1 hurt that bit more.
"There is very little possibility to overtake around here, so we will need to see what we can do with the strategy in tomorrow's race."
Mike Krack, Team Principal
"Days like these show the grit and determination of the whole team. Lance did well this afternoon to progress into Q2, ultimately ending up in 14th position. But we did not have the pace to be in contention for Q3.
"Sebastian had a difficult day. After hitting the barriers at the end of FP3 and damaging his car, it was a race against time to have everything ready for qualifying.
"But, once again, our mechanics worked faultlessly to fix the damage. They got the car ready ahead of Q1, but Sebastian unfortunately finished up in 18th place.
"These positions leave us with a lot to do tomorrow, but, with changeable conditions still on the cards, anything could happen."
