it would be very solid and hold the engine in place very well, but it would cause an extremely annoying vibration thougout the entire car. you would be able to feel your engine idle and it would def. vibrate the car at take off. this would be too stiff for comfort, and may cause unusual wear to certain parts of the chasis. the Brashboy damper has a shock to atleast absorb the more violent vibrations, a direct rod could be devastating.
