number 2 - I'm not sure if it's a track rod (like you mention it doesn't have any possibility of change the trackrod length) or a wishbone cause Ferrari have already used 2 element wishbones, instead of a complete wishbone.
I think that it's real PUSH for toe In 'cause inside it has wire connecting to wheel in one side, and other side wire must connect to gearbox. It'll be strange to do it using main PUSH. In this case yoг wire must be at the upper side of gearbox and must be connect to some holder near rocker and other moving parts....

It's very easy to produce wire inside Toe in Push whithout problem that you have in other case.
(But How guys change leight????? ) :lol: :lol:

What you call a toe in push....isn't it the same thing as a track rod? at least by the name you're giving it sounds like a track rod.

I'm putting my vote for 2 being a track rod, or push toe in or whatnot. If you notice on eitheir side of this rod that whatever is used to make the joint has screws in them, these machined holes could easily be machined with different positions of the hole and changed out simply by the screws. We use a similar concept in stock cars when mounting trailing arms and a-arms. So changing the front end geometry is as simple as replacing a slug with a hole in it. Eitheir that or they could show up at the track with different sized track arms and use as nessasary.

1 is the lower rear wishbone
2 is a track rod, the "wire"is the tether to keep the rear wheel attached in an accident.
3 is the rocker to operate the rear damper\torsion bar
4, The cable is the tether to keep the rear wheel attached in an accident.
5, This is the connector to link the senros on the upright, i.e brake wear, temp etc to the ECU
6, these are the preload adjusters fro the rear torsion bars
7, Rear rocker pivot connects parts 3 & 6, the torsion bar torsion bar fits inside

The upper wishbone and pushrod are missing, both of these have bolt on attachments to fix to the upright and rocker (repsectively) shims are fitted in between these parts to adjust camber and ride height

Ferrai guys have 30 spare push with 0.1 mm difference in lenght )))

They change whole push. :lol: :lol:

1 is the upper rear wishbone. From the F1-2000 or F2001, they are basically identical. The lower wishbone was totally different with a smaller angle included between the arms and the rear arm circular for most of the length.

2 is the track rod from the F1-2000 (in the 2001 the chord in the central part was longer and even longer on the F2002/3/4 where it basically acts as a diffuser extension). As for toe regulation, come on guys, think about it, isn’t that difficult...

3 is the front rocker (the rear rocker is a bit different and the gap between the two plates is a lot larger), from the F2001.

6 the one with the number is the front ride height adjuster from the F2001, the other one is probably a different versions of the same part (general dimensions are quite similar).

7 connects the rocker with the torsion bar. The parts are very similar front and rear.

Aren't the ride height adjustments made on the pushrod?

Yes ride height adjustment are made through the pushrod, or torsion bar to be more exact, as there are connected. I could see the bolts from 6 as being used to increase or decrease the preload on the torsion bar effectively adjusting ride height.

It was bought up a while back in the convo, but anyway.

A FSAE team used a CF tub and attaching suspension fixtures was very simple. They drew a slightly overbore hole, used some resin, and used packers decreasing in surface area to distribute the load evenly and reduce fatigue at the bolt hole. It was very simple and elegant and worked a treat.

Given the solr car wouldnt be generating the cornering loads a FSAE car would (I assume most loads would come from bumps?) this approach to mounting components may be ideal.
