The Pole said: "On a street circuit it is of major importance to have a good basic set-up which is easy to drive.

"The lap time improvement has to be gained step by step, you cannot drive in too wild a style. Also, in terms of the racing line you have to approach this gradually.

"It is very important to walk the track before driving it the first time to get a feeling for the surface and the layout."

Kubica added: "I am very much looking forward to Valencia as I am a big fan of street circuits in general.

"They are very demanding as they are often bumpy and the street surface changes. When you make a mistake you easily run into barriers.

"Anyway, Valencia will not be a complete street circuit. There will be lots of run-off areas for safety reasons. The FIA puts a lot of effort into safety, which is good."
