I've never driven a car with that kind of suspension, does the design still use caster to self-center the steering, or will the tires stay roughly where you point them even if you let go?
It does tend to be more apparent in front wheel drive cars, perhaps it's the weight of the motor? It's really important to get right in motorsport, as it denotes the characteristics of the car when you've oversteered. A car with correctly set caster will "self steer" itself back to straight without any driver input, and it will guide the car while oversteered in a way that's balanced with the direction the car's actually heading rather than where it's pointing (if you're intending to be sideways, like in drifting).
