Didnt see if it was jensons og hamiltons car but it definitely looked like they are blowing both elements on at least one of the cars.

Looking at the few threads on the hub to locate the lug nut , I wondered what happened to the old MSA regs that required the lug nuts to locate on the bolt /stud etc at least 1 1/2 times the bolt/ stud dia . i.e 12mm bolts/studs should locate 18mm into the nut.

Button has nothing to lose, so i think he can gamble on the parts.
Hopes it doesn't detract from meaningful testing in practice.
Any shots of new parts?

A picture in F1.com gallery shows Hamilton still using the F Duct blowing the main plane, not the upper plane.

Looks like button tried both types:

didnt they say the rear wing was called the rw80, when the bbc asked what the name for the f duct was?


so whats this wing then..

RW (rear wing) 80 (80th design/update etc)

notice RW75 in background.

I thought the number was a reference to the downforce. Engineer to mechanic, "we are gonna change the rear wing, take off the 80 and get a number 75 out of the truck, please".
Or in this case, get a 75 of the old wing ...

Rear wings aren't much adjustable anymore, they all come into the garage preset at their respective levels and angles.

lol yes i noticed it said rw75 in the background.. bt like i said i thought it was called the rw80, so is this an older wing or what?

It would make more sense if it was downforce. interesting.

I'm pretty sure I heard a McLaren employee (Whitmarsh, or maybe Button) during an interview joking that everyone outside the team called it an F-Duct, but they called it RW## for rear wing iteration ##.

Just heard from the Swedish broadcasters that Button is trying out a new electronical brakebalance adjuster that isn't really working that well. Any more info on this?

Sounds a bit like grasping at straws with the weight distribution and tyre balance problems.
