As I remember of 1988 honda prelude, it has 4WS, it has two mode. One is low speed mode(for parking and low speed)(the front and rear wheel steer at oposite direction). it made the car easier to turn, but easier to cup4 when the car is at high speed. The other mode is high speed mode(for high speed)( the front and rear wheel steer at same direction). it made the car more stable during high speed turning.Anyway, youi car is interesting, good job.
