Cerbera Suspension

I have just purchased a Cerbera V8, and find that it tram lines like a b

Has anyone got any experience of changing castor, camber or KPi inclination, or wishbones?
I have been told that it should be possible to get the car to drive straight, regardless, without changing tyre width or depth?
Any suggestions?

Knobby, if you're running standard sized,good condition tyres on the correct wheels then it can only be geometry. IIRC, the caster isn't designed to be adjustable, however, it's probably worth checking again to confirm that it's about right as it has a big impact on the ability of the steering to self centre.
Can you post up the figures from your 4 wheel alignment?
One other thing - what tyres pressures are you running?

Mine developed the tendency to tramline in Lorry depressions but had fantastic directional control on flat roads and a superb turn in characteristic. Fronts wore out on the outer edge.
Just changed the tyres and had the toe-in checked and it was 1.17 deg, The recommended was between 0 and 0.17 and the testers changed it to 0.07.
The tramlining has dissappeared but the car doesn't feel too uni-directional at speed and I am constantly having to re-correct.
Think I'll go back to tramlining

the above sounds like you reduced the toe-in and yet got worse turn in rather than better.
In my understanding your experience is the complete opposite to what you should have experienced.
Toe-in = Stability Toe-out = great turn in and response.
Hmmm I'm confused!
