Nico Rosberg has admitted he is travelling to Istanbul this week with an eye on the Turkey track's famous Turn 8.
The high speed corner is a multiple-apex left hander that concerned F1's new tyre supplier Pirelli so much that it recently tested at Istanbul Park and considered introducing new super-hard tyres to cope with its demands.
Ultimately, drivers will have to cope this weekend with the now-commonplace soft and hard tyre compound selection.
Asked about Turn 8, Mercedes driver Rosberg is quoted by sport1.de: "It's a very, very long corner and who knows what's going to happen with the tyres.
"It's going to be extremely stressful for the right front in particular," he added, after the first three races of 2010 saw the same Pirelli tyres degrade quite dramatically.
