Sahara Force India completed a routine day of free practice at Suzuka ahead of Sunday's Japanese Grand Prix.

Adrian Sutil: "I always enjoy this circuit, but today the car was not so easy to drive. I was suffering with understeer this morning and oversteer in the afternoon, and it's hard to find the balance I feel comfortable with. We need to try and solve those issues tonight to give me confidence going into qualifying."

Paul Di Resta: "The car was quite difficult to drive today, but we've worked hard to try and optimise the balance. After each run, we changed some things and I think we've learned a lot as a result. The long run consistency seems reasonable, but we need to make sure that we can deliver the performance with both the medium and the hard compound."

Otmar Szafnauer, Chief Operating Officer: "A busy day of work at Suzuka and we've tried hard to dial the cars into this very technical lap. The morning saw us evaluate some downforce options before we focussed on improving drivability. It's a track where driver confidence is the key to getting the lap time and that's where we will concentrate our efforts tonight to give Paul and Adrian a better balance for tomorrow. The initial indications are that the race pace looks competitive along with the tyre degradation rates."
