Charles Pic says he is pleased with the improvements Caterham has made with the balance of the CT03.
Pic was twentieth in second practice, ahead of team-mate Giedo van der Garde.
"We found a balance that worked on both compounds quickly, so we were able to get everything we could out of both sessions," he said.
"We didn’t have any issues that held us up, especially compared to the number of small problems we had in FP1 and FP2 in Spain, so that’s put us in a better position for Saturday and Sunday than we’ve been in all season."
Van der Garde says his runs were compromised by Romain Grosjean's accident.
"We went onto the supersofts and waited for a gap in the traffic but then on my quick lap the red flags came out when Romain’s accident damaged the barriers," he said.
"That was bad timing as I was definitely on my fastest lap of the day and I think we’d have been looking at a time around the mid-1.17s, more representative of our real pace today. But, FP1 and FP2 aren’t about the quickest laps. They’re about what we did today which was work through the program, start to understand how to manage the tyres and generate as much data as we can for the guys to work on at the track and back at the factory."
