After a nightmare begin to his maiden season within the DTM in a buyer ART-run BMW M4, Kubica lastly broke inside the highest 10 within the first race on the Dutch venue on Saturday, scoring his first factors end of the yr.
He appeared set to copy that lead to a moist Race 2 on Sunday, having certified a career-best tenth and overtaken WRT Audi’s Harrison Newey to run ninth early on.
The Polish driver stopped for contemporary moist tyres after simply 5 laps of inexperienced flag working on the finish of the seventh tour, and returned from the pitlane on an empty monitor.
But Kubica merely couldn’t present the identical tempo on contemporary moist tyres as he did within the first stint and he finally slipped to fifteenth within the remaining classification, solely forward of a lapped Newey.
Speaking after the race, the 35-year-old felt he might have completed greater up the order had his crew fitted his automotive with low stress tyres consistent with the drying monitor circumstances.
“It’s a bit of a shame because we talked about it before the race, we did everything perfectly and we decided what we had to do,” Kubica instructed Motorsport.com.
“Although we didn’t have massive pace, still the second stint was so bad because there was a mistake on which set [of tyres] went to the car. When you have this condition it is important to have right pressures in the tyre and the pressures were a bit incorrect.
“You prepare different sets with different pressures and depending upon how much water you see [and] what is the weather. But it was clear that we would stop early and we would go long and the track was drying up and we need as low pressure as possible.
“Unfortunately when I came out after one lap I discovered, because the team cannot tell you that. By feeling you know something is wrong and the only thing that can be wrong is this.”
Kubica’s technique to make an early pitstop might have been a masterstroke, as manufacturing unit BMW driver Sheldon van der Linde, who stopped simply three laps later than him, went on to win the race from 14th on the grid.

“For me it’s clear that working off site visitors on moist could be useful and appears like folks on a drying monitor there may be plenty of potential, plenty of velocity distinction within the vehicles and so they have a tendency to dam one another. When you might be in clear air you are able to do your individual race.
“I’m certain he gained various time and the place. For me in the long run it was simply lack of tempo. I had Sheldon popping out from the storage just a few laps later, he simply pitted in entrance of me. If I’d have the tempo we most likely end… in the long run the choice was made earlier than the beginning of the race, we simply didn’t have the tempo.
“After two laps my rear tyres had been far and wide, the automotive was not dealing with [well]. We know the explanations. But that’s how it’s.“
