Multiple Choice

The vehicle thrust line is determined by:

The thrust line is the path along which the propulsive forces from the drivetrain act on the vehicle, essentially set by how the rear wheels are pointed. The rear toe angle determines where the rear wheels point relative to the vehicle’s centerline, so it fixes where the drive forces push the car laterally. If the rear wheels are toed in, the thrust line shifts inward; if toed out, it shifts outward. Camber, the vertical tilt of the wheels, affects tire contact patch during load and cornering but not the direction of the propulsion force. Caster is the steering axis tilt that mainly influences steering feel and return-to-center, not the thrust line. Front toe affects straight-line stability and steering response from the front wheels, but the thrust line itself is defined by the rear toe setting.
