Japan Friday quotes: Spyker

Adrian Sutil - 16th: "It was very much a normal day. The track is very good and it's a lot of fun to drive here with an F1 car. This morning I had a better feeling but we have a lot to do for sure

"We had some problems with the harder tyre, they just don't seem to be able to keep their temperature or suit the track conditions. The softer tyre seems to be better and I set my fastest laps in both the sessions on this compound. Every team needs to find a good set-up, but hopefully we can find half a second or so."

Sakon Yamamoto - 20th: "It was the first day for my 'home' Grand Prix. In the morning I had an engine failure and had to stop, which was a bit of a shame as it was the first time we had run here and we wanted to put in as much mileage as possible. But in the afternoon I think we did quite a good job as it all went to plan and I think we have some good data for tomorrow."

Mike Gascoyne, chief technical officer: "A very productive day with both cars. Sakon lost a little bit of time in the morning session with an engine problem but apart from that we had no real issues.

"The new aero parts we brought over here seem to be working well and we seemed to have taken another step forward in comparison to the teams around us. I hope we can look forward to a very good weekend."
