Re: Raikkonen spinning, I would have thought that would be too much rear bias, not too much toward the front?

Yeah, it might be rear brake bias. Or it might just hit the wet kerb with the rears. I don't think there's too much read into it. It can happen.

Re: Raikkonen spinning, I would have thought that would be too much rear bias, not too much toward the front?

No, it's opposite.

No, he's right, if you loose rears on braking then you locked them, and you can lock them dure to rearward bias.

[infy]

It could be a few things really. Bias too far rear, a sudden loss of rear downforce, sudden increase in torque caused by a downshift slowing the rear wheels or the simplest of all, Kimi may have not released the brakes fast enough to compensate for the lack of downforce in at corner entry.

I agree. My mistake.

Not necessarily, it could also simply be a case of no wheels locking, but one set wanting to slow faster than the other. We didn't see any smoke from a lockup, so I'm inclined to suggest that the fronts simply wanted to slow faster than the rears, and that he hit a bump/something else unsettled the car slightly.

Don't forget that the rear braking is much more affected by ERS that it has been in the past.

I was talking about the idea that the spin was caused by brake problem, if that was indeed so, it was clearly the case of too rearward bias, btw, you don't have to lock anything, it's just that if you combine braking and turning and much of grip capacity of the tyres is used by brakes than the lateral forces would cause tyre to slide.
However, I agree that it might not be the case of any brake problems as I noted above.

Ferrari has considered 'dozens' of noses

http://en.espnf1.com/ferrari/motorsport ... 43703.html

Ferrari technical director James Allison says his team has looked at dozens of different nose types for the new F14 T, but has played down the importance of the nose for overall performance.

"The reason there isn't a single solution is it's not actually that sensitive an area, so there are lots and lots of different solutions that work. I came from another team before that has a very aggressive solution; I worked on that with the team and this car has got another solution but there's really not much in that. They're just things that are good to talk about because they are right up at the front of the car."

So they already bolted a new diffuser..

[lombers]

I really dont think the nose is as contradictory as everyone is saying. the tub is still very high, and we saw from the flovis, it goes round the first part of the nose, not up and over.

It's interesting because I asked Scarbs on twitter what he thought of all the discussion regarding the new noses and their effect on the overall aerodynamic package of the car. His response was:

they're not as important as the attention they draw. details around the sidepods and back of the car are more critical

I would agree with this statement, I don't think the different nose solutions will have significant effect on the aero packages of the 2014 cars. From an aesthetics perspective, well that's something completely different altogether

So they already bolted a new diffuser..

well, it is called testing...they are testing different parts to see which one works better, to compare results from wind tunnel and CFD to those measured on track,...

But they've been working on it forever, it should be perfect out of the box!

Via DAMNINice and posted on Mercedes thread, a relative information regarding brakes and why Raikonen might have lost the rear on that video

"Rosberg giving his opinion about new brakes.

Q: How is it driving the "brake by wire system"? Do you feel confident braking?
A: "It´s complicated to describe. the front is a standard brake. Only the rear is nearly completely braked by the ERS. On high speeds you have plenty of downforce so you have a fully angaged rear brake. It´s like using the handbrake on a normal car.
When slowing down the car, the downforce is lower so you have to release the brake. To set this up is really complicated. The balance between the mechanical front and nearly completely electrical rear brake is key and complicated. At the moment it´s not perfectly adjusted. I don´t know what I´ve written but I hope you´ve understood "
