Build continues here are some photos of the fixing points and set up.

The idea is to get the front and rear mounts as far apart as you can, and the top and bottom mounts as far apart as practical.

Sidecar wheel lead is important for handling and stability I set mine at 300mm in front of the rear centre to centre. with 35mm toe in measured at the front wheel spindle

Lean out of the bike away from the chair varies but I set mine at10mm at the top of the wheel rim. This varies with the suspension set up and weigh of the rider etc.

The chair frame should be sitting parallel to the ground

The object of the exercise is to be able to modify and fit whatever you need for set up with out upsetting the bike or cutting body panels

Once its all together you hardly notice the sub frame.
I will post more on this later.
