Anybody got any ideas of the best way to adjust the toe on a double wishbone rear suspension on a Locost, rose joints? ball joints?

is this a existing car or one you are building now?

This is how I set mine up and its been ok as a starter.

You can use washers between the hub carrier and the hub to set the toe, the Lightning Rod oval racers do this to get rid of the camber and add some toe to make the cars turn in better.
When you get the toe where you want it you can then get the hub carrier milled and dispense with the washers.
