that´s from Canada right? I think it was introduced there but had no idea they kept it for Europe.

The update was originally introduced in Canada. But this analysis is speaking of Valencia. So yes definitely used last weekend.

ok thanks, thought it was specifically made only for Canada due to the nature of the track,

I mentioned in the start of the season that i believel McLaren would have a good advantage if it had had pullrod front suspension on the 27. Because of its allready low nose. Pullrod you further lower the CoG on the front.

Im pretty sure that all the difficulties Ferrari had in the start of the season was more related to the rear of the car. Both suspension and aerowise.

Im guessing that more than 2 teams will have front pullrod next year.

[Lycoming]

He's not seeking pullrod for the lower CoG. The advantages in that department are minute, as you have to strengthen the upper wishbone, which moves weight back up.

Like ferrari, if they do it, it would be for some kind of aero gain. As I understand it, the aero advantage ferrari gets from it is having it almost horizontal, which means it interacts with the front wing's wake in a more favourable way. Having the lower nose may not really make it any more suitable, as it could result in a larger angle on the pullrod.

On the flipside if you have a less extreme angle, the rod could theoretically be thinner, though the gains in that department are probably the most marginal.

Either way you look at it, the gains are not large, even by F1 standards. But its not a spectacularly difficult job to make it work, so I guess I won't be surprised if teams decide to move in this direction.

On the topic of low noses we still dont know if FIA is gonna push 2014 nose regs to 2013 to solve the step issue.

[Holm86]

Why would the upper wishbone have to be stronger in a pullrod configuration? I dont get that.

Do they bulge the lower half of the pull-rod to give it a cross-section like an inverted airplane wing?

[marcush.]

speaking of anti dive and antisquat geometries...why restrict yourself in the first place and controlling these by geometrical effects instead of controlling the suspension vertical response just with dampers and springs?

[PhillipM]

Why would you consider that a restriction?

No, they must be symmetrical as well as adhering to a pre-defined aspect ratio limitation. Ref tech regs 10.3

To control the pitch (and roll) with springs/dampers only would require very stiff springs which is bad for the tyre in terms of road-holding (increased load variation).

Introducing anti dive and anti roll (roll centre location) diverts the pitch/rolling forces through the chasssis and suspension links and away from the springs meaning they will deflect less than the case with 0% anti dive and rch=0. This means you can use softer springs for the same amount of body movement.

Has anybody got an information what develops they will have in Silverstone?

[myoozikk]

Germany is the race to be looking out for.
