Mark going back to his roots in GT racing maybe good for him, he can satisfy his racing urge and have a shot at winning, I really like Mark and have always been a keen supporter of his abilities, but his time at Red Bull is up due to the team not handling things between him and Seb very well.

Mark was always number 2 when Seb arrived, if he never slipped up in Korea that day he'd of been champion, that will be his greatest rue. 

I hope Mark stays longer in F1 perhaps Ferrari because him and Alonso are great friends and that'd be a nice environment while Bianchi develops, but I can't see him staying in F1 which is sad :( 

1. It's a get a move on signal, being at the back and behind your rival team who seems to have a good thing going with Jules Bianchi and KERS, Caterham might have to get drastic.

2. 2. He seems to consistantly beat JEV and seems to have a good grip with this car, I'm hoping that he can prove that he is worthy of the promotion but with Kimi being rumoured he'll have to really prove himself.

3. Both penalties were deserved, Mark's incident was an avoidable collision so therefore the penalty had to be given, as much as I really feel for Mark in his current situation but I do feel he will leave at the end of the season.

4. With the high temps which predict 35C for race day, those soft tyres would perish in a a lap if that, the tyres now ahould hold up, but I reckon a one stop from top teams because of how hard the 'Prime' tyre will be.

5. I'm not a huge fan of the Bahrain circuit, and I agree after last year it's tricky for teams and personel to stay safe. I hope the weekend goes without a hitch, but I feel Bernie needs to look at other circuits around the world to go to. 

This is true, but the track layout suits Red-Bull i think, but i think come race day Everyone else is gonna be right with them, Lotus and Mercedes are good in a straight line where Ferrari I notice are strong all-rounders, as my prediction i've said Vettel will win, but i'll be honest could be anyone and it'll be a close fight all the way.

Red Bull are hardest on their tyres that'll be there biggest disadvantage in the conditions.

Formula 1 tyre suppliers Pirelli will not use their soft tyres at the Bahrain Grand Prix this weekend after concerns about how quickly they wear out.

No driver managed more than seven laps on one set of soft tyres at the Chinese Grand Prix last week.

"Bahrain is one of the most demanding tracks of the year for the tyres, mostly because of the high ambient and track temperatures," said Pirelli's motorsport director Paul Hembery.

"We expect about three stops per car."

Tyre degradation is expected to be reasonably high during the race in Bahrain, the fourth grand prix of the 2013 season.

Red Bull's Sebastian Vettel leads the drivers' standings after three races, with Lotus driver Kimi Raikkonen second and Ferrari's Fernando Alonso, who won in Shanghai last week, third.
