Kamui Kobayashi says he hopes to resolve understeer problems which plagued his Caterham CT05 during second practice for the Bahrain Grand Prix.
Kobayashi sat out the first session to allow Robin Frijns some track time and the Japanese driver set the 21st quickest time when he returned to the track.
"After sitting out FP1 I was keen to get back in the car, especially with the better reliability we had in the first session which will help us much more over the rest of the weekend," he said.
"The car felt okay but we had understeer in both the low and high speed turns so we tried a different front anti-roll bar for run two and there was a small improvement, but there was more front locking so I couldn’t really attack into the braking zones."
"On the softs the car felt better, but it was very snappy on power. On my first quick lap on the softs I had traffic and I had to lift for yellows in turn four, and then again the next time I went for a quick lap so I think with a clean run there was quite a few tenths left in the car, but we didn’t have a chance to improve that as we went onto the long run for the final stint, starting on the mediums.
"That went okay and we finished Friday with a good number of laps for the first time for me this year.
