Kobayashi struggled during Q2, having narrowly made it out of Q1.
"I have been struggling with the balance of the car since we got here. We did a lot of changes and managed to improve it to a certain extent, but I still had problems with the front brakes locking", he said.
"This was also the reason for the mistake on my final flying lap in Q2. I hit the brakes, the front wheels locked and that was it. I think in race conditions we should be better, but it won’t be easy to improve. The circuit allows for overtaking, but you also need to have the speed for it".
Sergio Perez was just over half a second faster than Kobayashi and will start from 12th.
"My last lap was a good one and I think this is just about the maximum possible for us here. Q3 today wasn’t within reach, although yesterday I hoped it would be. I have confidence in our race pace and believe we will be able to score points tomorrow", he said.
