extending or contracting steering arms in same direction, independent of pinion rotation, causing the wheels to rotate in opposite direction to each other is not steering. that is toe adjustment.

Thanks for posting.

The legality has not been tested as yet. so far opinion and "monitoring"
hence James having to put out the "confident" "positive" promo clips telling all its steering....
But steering means change of direction?

[Zynerji]

So, this could be a simple lever in the steering rack that pulls both steering arms in simultaneously?

Doesnt seem like it would take a ton of effort to make it work, but could take lots of simulations to make it perfect.

Just wait until TAS, so tilting the wheel left or right can bias the DAS to one side or the other...

imo its legal, in the rules but out of the spirit of the rules
we are in the hand of FIA..

Not much room in the bulkheads, how much time for a chassis redesign and crash tests if needed? And would they go through the trouble to do it with a big regulation change next year??

[Zynerji]

Lotus redesigned Kimi's steering rack in a few weeks. I dont see why this would be a chassis change at all.

It would probably bolt right on to the RP20...

There's a huge difference between altering the rack internals for feedback and making the entire rack slide and the associated room it requires. Making the thing is easy, they could have a prototype up and running in a couple of days, probably a production one inside a week, but packaging into the existing car will take far, far longer.

Very simple. telescopic steering arm, extended and retracted by hydraulics. master cylinder on steering wheel shaft.
pulling wheel displaces piston, transfers pressure to cylinder in steering arm, causing it to extend or contract.

can be implemented in 6 weeks.

Very much what I think as well. It's probably just a removal of some fluid between the steering arm pistons.

Nothing has to slide. It's just changing the distance internally between the steering arm pistons.

[PhillipM]

I can't see how that would work whilst keeping the pistons connected to the rack, if you use floating pistons you'd only be able to attach one side to the steering rack so it would only work on one side.
I suppose you could run the pistons inside the rack cylinder itself but the moment you moved the pistons away from full extension the steering would float all over the place.

As per regulation, the rack assembly can not "slide" and it has specified mounting restrictions. all that is happening is telescopic adjustment of the steering arms / rods as some call it.

Literally the perfect time to pull out this Newey quote.
