Sauber has good memories from last year's first Korean GP says tech boss James Key.

James Key, Sauber technical director
We have got some quite good memories of Korea from last year. It’s obviously a neat track. It took a bit of work with the very low grip levels on the very fresh tarmac, but, once the track rubbered in, it turned out to be a good circuit which the drivers liked. It seemed to be quite technical with two long straights, but then you’ve got the relatively winding sector towards the end of the lap, and then some high speed corners before the last straight. So it’s a really good mix of corner speeds that will probably require quite a different set-up compared to what we were using in Suzuka. Last year it was extremely wet, therefore we haven’t experienced a full race distance in the dry, so we don’t fully know what to expect from the tyres, which will be the super soft and the soft compounds.
