You mean the lower "rounded rectangle", don't you?

The track rod is the upper one. The lower one is the rear arm of the bottom wishbone. The highlighted piece in the photo is the entirety of the upper wishbone.

Rules do not allow 3-member wishbones.

Toe link.

And maybe it is the other way around, I haven't seen a good enough picture of the up right without a wheel on attached.

Which part of the rules say you can't have 3 armed wishbones? I understand you can't make redundant wish bones, but if it's a single part it shouldn't be a problem.

Toe link.

Sure thing.

The rule is you can't have redundant members, not wishbones.

What constitutes a member? If it's a single part I don't seem the problem. It's no redundant if it's structural.

Also it is the toe link, why don't you believe me? Track rod is on the front, for steering...

The rules say that they're considered individual members even if they're moulded as one.

I believe you. Most people where I live call them track rods, even if they aren't. The front they call tie rods. Hillbillies, what can I say? I'll call it a track rod or tie rod or toe link at random. Whatever word comes to mind first is the one that gets typed.

Actually, I rarely if ever use toe link.

It's the thing that makes the wheel not wobbly.

were there any components/parts banned on last year's car just before the season started?

you could say that about every link.

I love chrome livery.

[Per]

The force in the pullrod is dominated by the normal load on the wheel so I can't imagine that the butterfly suspension will have much influence on that.

It's also determined by suspension geometry, particularly pullrod angle.

Of course but that doesn't seem to have changed much from last year.

And with rear downforce reduced w.r.t. 2013 the normal load should be lower.

but weight is increased. Plus, your largest load is going to be in bump anyways, and the bump load is large relative to the downforce load, so it dominates.

Downforce is way more important than weight. But you're absolutely right about bump load, I forgot about that one.

Perhaps they are using some temporary pullrods allowing for greater ride height adjustments? They look like metal and I can't imagine McLaren not using CFRP pullrods in Melbourne.

I don't understand how metal pullrods would give you more ride height adjustment options.

Like I said, maybe they quickly made something that provides more adjustability than what they typically use in a GP weekend. Easier to make something quickly out of metal than out of carbon, and those few hundred grams (if the difference is really that much) won't matter so much for testing.

The rule is you can't have redundant members, not wishbones.

If I'm not mistaken there can be only a maximum of 6 "members"
- 2 "members" for each wishbone
- 1 Track rod/toe Link
- 1 Pull/push rod

Is the Toe Link acting as pull rod? Or am I missing something?

No, the pull rod extends forwards and inwards from the wheel to end at the floor under the side pod. The toe link extends backwards and inwards, and forms the lower of the louvres.

The toe link controls the toe, i.e. it keeps the angle of the wheel constant if you look at it in plan view (simply put it prevents the wheel from steering).

The pull rod is what carries the vertical load on the wheel.

Louvres? Are you referring to the "mushrooms"? In that case they don´t have a separate toe link?

[Per]

The toe link is the UPPER of the two 'mushrooms'. It is clear in this picture posted earlier by Owen.C93: http://www.formule1.nl/media/uploads/me ... 593.49.jpg

Here you can clearly see the upper wishbone consisting of two normal members. Behind the upper wishbone is the toe link, which has the bell shape.

The lower wishbone has a normal front member and a bell shaped rear member.

I made those bits...

The others keep the wheel from being floppy. Or detached.
