Self centering

[robo]

If you have a dig about on here someone did an explanation of all this. The mushrooms dont add caster they give you trail. Its this trail that helps with the self centering, a bodge is a better word for it. There is not enough caster in the front suspension set up and no way to alter it.Thats why I am making my upper bones with adjusters on the inner joints. When they are on the car I will take some measurements of them in the corrected adjusted position then perhaps someone can do an ammended top wishbone drawing so they are built to include the caster without the need for adjusters. Caster is an important must have for straight line stability not just self centering. I am no expert on trig but i bet its only a few mm added to the front top wishbone tubes to sort it.
