Hi Paul,
Being back in Oz for a few months has allowed me to do a fair bit of driving in the Cobra, didn't get home at all last year and the poor thing sat in the shed
I felt that the car was a bit darty on the road and wasn't entirely happy with the self centring of the steering. Anyway after some consultation decided to add caster and get the balance sorted.
Simply installing the adjustable radius rods added considerable caster but pulled the wheel too far forward in the arch. In the rally cars I used to play with we used adjustable radius rods and adjustable tops on the MacPherson struts to achieve camber/caster. So to move the upright aft new top wishbones were fabricated with offset built in.
On the drive home the car seemed more planted. Unfortunately the speedo lights and the temp gauge played up so I've had the dash partly pulled apart hence unable to go out for a drive since. Hopefully Thursday the missus and I will head down the coast for lunch.
Cheers
