Front right wheel picking up and tripod'in the car.

Anyone else seen this sort of thing in F1 before? They must be running an extremely stiff setup. My car does it on track all the time when pushed hard but its what happens to 106/Saxo's with stiff setups

er It's nothing new in F1 - I have seen f1 cars in the past do it at various tracks.

Monaco for example.

The McLaren was doing it last year with the front.

It is either a useful tyre saving technique.;)

Or the free wheel itself is being used at these points as a aero dynamic device.;)

It has absolutely nothing at all to do with the suspension!

I thought I saw Alonso's car doing it too. Presumably it must mean soft at the rear, stiff at the front. Or rather not as much drop at the front as there is compression at the rear.

Monaco through Mirabeau is one thing

Out on medium speed corners is another

It suggests they are setting up the rear quite soft / front stiff to compensate for a late of grip at the back end

It's been documentated that they used a used stiff front end last year as an inherent characteristic of the car, mainly to suit Lewis' driving style - sharp turn in and deal with the oversteer through to the apex

But that today did look extreme to me

I think if the front wheel is lifting it means the rear suspension is relatively soft and the front is stiffer.

Wurz mentioned it in Oz IIRC.
Very soft at the rear compensating for the lack of downforce.

I seem to recall MS did it in Hungary one year.

And Belgium in another

That also had nothing to do with anti roll bars and spring rates...

thats how i understand it, stiff at the front to try and help maintain optimised aerodynamics into the air, soft at the rear to try and make traction a bit easier to retain out of the corner*.....its a compromise but then again it always is


*i stand to be corrected of course, it could be a crap tub that's flexing with power torque or it could be some wild illegal gizmo thingy :lol:
