Malaysian Grand Prix - FP2 - Webber said " "We look okay, but it's still early days in a race weekend,"

Mark Webber is not getting carried away with his headline times during Friday practice for the Malaysian Grand Prix.

He topped both sessions, the first one by over 1.5 seconds and the second by just 0.005 seconds. His closest competitor was a McLaren on both occasions and while he was happy with the extra laps the team completed on Pirelli's 'super-hard' development compound.

"We look okay, but it's still early days in a race weekend," Webber said. "We got some dry running in and the car performed well. It was reliable, which is always a nice bonus. We got to check all the tyres - including the new tyre that Pirelli brought here. It's very hot. We need to look at the information we got today, but so far so good for us."

Sebastian Vettel indicated that the only concern could be tyre degradation in the intense heat expected on race day. But he does not think Red Bull is any worse off than its rivals.

"We completed quite a lot of laps this morning because of the extra tyres - and this afternoon we did more or less what was planned," he said. "We didn't have any big problems, but we got a lot of mileage and took a lot of things onboard. Obviously tyre wear is different here to Melbourne. I think it's the same for everyone, at least, it is for us. We'll see where we are tomorrow."

The team ran KERS during the practice sessions but will make a final decision on its use this weekend tonight.
