David - 1.5
degrees toe in are you sure
no wonder it's twitchy as hell I would have thought 10 minutes total toe in for the front and 10 - 20 minutes total toe in at the rear at the most.
I've looked up dozens of car geo specs but could find nothing that drastic on toe!
If the Haynes roadster needs that much toe in then theres something seriously crapped up with the suspension design
I would treat 20psi for tyre pressures as a max value as well, my MX-5 is only 26psi and it's nearlt twice the weight
