Lewis Hamilton has hit back at his critics today by comfortably setting the fastest time in both practice sessions. Both McLarens have shone today with Button coming in 3rd and 4th for the British outfit in a hot and humid Malaysia. However Jenson Button says he has been struggling with the balance and set up of the car, something that he isn't good with adapting to.Lewis on the other hand set the quickest time of the day with a 1:34.175 was .266 seconds quicker than second placed Sebastian Vettel. Red Bull however have had another day of reliabilty problems. In Free practice 2, Webber went off with a suspected engine/gearbox failure and Sebastian Vettel, the favourite for the race complained about a lack of power steering. So the difficult season looks likely to continue for Red Bull. Webber finished 20th with his team mate again driving strongest with 2nd. Mercedes had a good day, In FP1 they had a solid outing with 2nd and 4th for Rosberg and Schumacher respectively. Then in FP2 they had another good show with 3rd and 5th. So things look on the up for the team. Whilst theres been a swap around with Ferrari as they see themselves look quite slow today. It is unclear whether they were heavy but there was definite problems with Massa's car, around the bottom of the diffuser area. Alonso came in 8th then 7th and Massa finished with 11th then 14th. So all in all, not a fast day for the scuderia although they probably did have more fuel. Although the team did say this on their twitter during FP2
