Singapore Friday quotes: Force India

Paul Di Resta - 13th: "It wasn't the best of days because what I really needed was time on track to help me learn the circuit. The first session was cut short and in the second I had a hydraulic brake issue, which took most of the session to fix. So it means that I go into Saturday with limited running on the soft tyres and just one timed lap on the supersofts. It's not ideal because you need to build your confidence on a street circuit and find the limits because there is little margin for error. On the positive side Adrian has shown that the car seems to be on the pace and I felt quite happy during the limited running I did do on the soft tyres."

Dominic Harlow, Circuit Engineering Director: "Slightly less track time than usual today during Friday practice, with the first session shortened whilst some damage to the kerbs was repaired, and with Paul's second session restricted by downtime while the team worked on curing a brake system issue. Nevertheless, it was possible to conduct the usual tyre comparisons and evaluate some new aerodynamic components on the cars. Because we opted to run our race drivers in both sessions today, we're confident we didn't loose too much and can recover any lost ground tomorrow. This circuit remains very challenging in a lot of areas and with some hard work to do before Sunday we can look forward to an interesting race."
