Scarbs story makes me think agaain:

If they are indeed not carrying as much ballast as say Red Bull their weightbias is most possibly more to the rear or maybe quite were it should be in theory .

my point is simple:what is there to find in terms of weight in the front ?A nose cone ,a wing 4 wishbones ,2 trackrods ,two pushrods a steering rack with servo ,mastercylinders and pedalbox plus steeing column and a steering wheel plus a bunnch of cables.... plus two wheel assemblies ..+ driver and the firebottle
Counting up the pieces my believe is that the forward weight bias is close to 35 % towards the front without resorting to ballastplacement I´d estimate.

so if we consider the loss of contact patch at the front and something like a weight split near 45% front in 2009..and a car weight of 605 kilos , around 60 kilos of ballast were needed at the front.Sounds reasonable.

for 2010 the minimum weight has increased to 620 all things equal that would be an additional 15 kilos to play with so you could move 75 kilos to the rear...starting with the aforementioned split of 35 %front on a unballasted car we´d arrive at a 31/69% split.. so without big drama Brawn could move the weight distribution dramatically from last year and surely more towards the rear than necessary...
so if really the Brawn carries a lot less ballast than Red Bull then we might see
a bit of light just why the car is lifting wheels and needs to resort to stiff setups to keep the platform stable..the CG height is to blame and it is not they need to shift weight from front to rear but from high to low at the rear ....to make the car more stable and transfer less weight in cornering....

IMO you guys are all missing it. I would expect that the problem relates to the positioning of center of pressure under the car, which is controlled by the design of the DD diffuser. The more forward you can get the center of pressure (low pressure of course) the more front grip you;ll have. Of course that also means optimizing packaging around the diffuser, which is one of those very hard to change kinds of things.

Really, how on earth could you guess that??

Read in a Bild article that the weight distribution since Bahrain has been changed and now the rear axle is now under increased pressure. It was a translation, but that's what was stated.

Thank you for this dren

[PlatinumZealot]

So they seem to have solved it then? We will see in practice. How comes nobody is posting pictures?

I think it's the tub, not directly, but because the tub determines how things are packaged longitudinally right?
Obviously the car was made short by moving the driver forward to get room for the tank and trim down the rear body work.
If you look closely you can see shumachers bum teetering over the splitter, driver placement could be the problem for the weight balance and under steer, who knows?
Secondly i don't think that the COG height is one of the major problems. It's not like last year where they had to improvise with the gearbox and Merc engine, so i think the team would be weary of COG height this year and probably go to extra lengths to get it as low as possible.
Visually i think the driver COG is too far ahead, affecting front aero, because the front has to be bulky to accommodate this, and affecting the balance because driver is to far ahead with such a short wheel base.


Merc need to get Shumacher's ass out of that area. Push it back and put the thy at a steeper angle to cut down the front end bulk. I don't think shifting the weight of the thy upward and having a minute increase in COG because of it will outweigh putting the COG backward for a better balance and the other aero benefits that come with it.
Then again this is all tub design, so i don't know if it can be changed, though increase in wheel base could effectively get some of these things done.

makes me laugh you guys trying to say this is how to fix the problem, leave it to the professionals they spends thousands hours in labs and wind tunnels analzying it all. they know a hell lot more than you, if that easy email mercedes and tell them how to improve the car

Thank you. Discussing aero is one thing, but to argue against the REIGNING WCC about the weight distribution and chassis of a F1 car that said reigning WCC has spent thousands of hours optimizing....crazy. I just think aero is the only area where spectators can comment with any true accuracy.

I think the splitter might make a ton of drag with very little df
the bottom one: how evactly does the shak gills connect to the exhaust, and the exhaust is back out of the engine cover again which i know is a big no no

There is a little cut to the exhaust (you can see it), so it belongs to the exhaust, like the Ferrari idea, they just copied it.

so does the slit go till the bodywork curves down for the vent

[ringo]

sneaky....
something being fed through the 2 hole here? So that's 4 holes to feed the diffuser?
Wonder where it leads to?


This winglet seals the floor? Brawn looking for central downforce?

Mclaren spent thousands of hours optimizing for the 09 car too

thnx for sharing, great detailed pictures.

[gibells]

I can't see that they've made the hole for the starter any smaller. Seems a bit sneaky to me. Also, that slit from the exhaust hole to that shark gill doesn't go all the way, therefore has to be described as 2 seperate holes. Would not be surprised if they get into trouble with the stewards because of these 2 things.
