You will need a specialist in suspension geometry and setup, yellow pages and such like are a waste of time, the answers you get from so called high or back street garages.
Not less than three times when treated like a total numpty-, "cant be done mate", i specifically asked have you got the equipment to test, I will show you how to do it?
Basically you could do it yourself if you can guarantee the ground is perfectly flat and level under the four wheels, i couldnt.
Some means of measuring the angle of the wheels, i had to improvise initially to get it something like along with the tracking since i would be doing around 1400 miles before i could get the car in and done properly. This is how i figured out, certainly on mine there is a visible serious positive camber when turning in effectively causing the tyre to skid and taking outer edge off. In a straight line and roughly 1/4 a turn of lock it has neg camber on the fronts, bad design someone got their equations wrong in the design dept.
