Kobayashi and Perez: We need to improve the set-up for tomorrow's qualifying

The "hot" comments from Kobayashi and Perez of the Sauber team after the two free practice sessions on the Sepang circuit for the Malaysian Grand Prix, the second round of the 2011 season.

Kamui Kobayashi – Pos 14:
“High temperatures make a difference. I can't complain about the tyres, they are working well despite the conditions. However, we are struggling with the set-up. The important thing is that we need to improve braking stability and I think that's what we are going to do overnight. ”

Sergio Perez – Pos 15:
“It's obviously very hot in the car, and it's clear that the race will be very demanding. My run on soft tires didn't go well because I had to return to the pits after a yellow flag. Overall I think we have some work to do to improve the car for tomorrow.”
