Hi Neil,NeilR said:
Your problem has attracted a lot of interest on this forum. Is it possible to describe the drifting problem in real world driving terms? It would be helpful to list: type of road(s); number of passengers; speed of vehicle; tire pressures; and a good description in your own words of the drifting that occurs.
Do you have a benchmark to compare to - such as another 300C or a different make of car? I mention this because all cars "drift" off centerline to some degree or another.
It must be frustrating to have a new car that you cannot enjoy. Hope this forum can help you.
