No, the 2mm spacers for the front roll centers. Appears to me that the rear has all of them below and the front has a couple above.

Yeah it looks rather like that. If this is correct, it is indeed a reactive caster adjustment.

Salven's car would have even less caster when turning.

Definitely a severe slope from high rear to low front. you explained earlier that the idea is to have the caster change as the car goes round a turn, but I don't see how unless the lower pins are also sloped. This lower pin is not clearly visible from the picture.

Julius ... any comments? Hints?

You'd still get caster change as long as the upper pins are sloped. You'd get even more caster change if the lowers are also sloped.

You're right! I was thinking the pivot balls will only allow the upper arm to rotate as it moves up and down but in actual fact as it moves up and down, it also moves from front to rear and back. Smart, very smart! :nod:

If turning right, left front wheel will reduce caster while the right one is increased isn't it?

Interesting! Has this been tried by anyone before?

The caster decreases when the suspension is compressed. So theoretically, the FL caster decreases while the FR somewhat stays the same.

Heres a link to a reactive caster adjustment and what it does:

Reactive Caster

Still remember those days when I drove the Evo2 with Pivot Ball suspension, while everyone at the track laughed at me for sticking with the PB suspension. At the same time, I kept kicking their C-Hub suspension cars, while they didn't know the how useful using the reactive caster was. And I was so amazed with it and how it reacted.

If it is a reactive caster adjustment on Salven's car and will get mass produced after the Worlds, take my word: GET ONE SOON !!
