How much neg camber & toe out for SVA for my Indy?

Toe out is quite subjective depending on how much self certering you think your examiner will want the vehicle to have when you present it. No use really but I would suggest you go for a drive (on private land of course) and try it out, and if it doesnt self centre to your anticipated satisfaction, add a bit more toe out, and keep trying until youre happy.

Toe out till it looks daft, neutral camber, max forward castor (mushroom adaptor eccentric hole to front), 40psi (dont drive with this pressure - blow them up when you get there).

Car will handle like a pig - pull the wheels in after test for drive home.
