I completely agree with tfosdick and MGXsport.
While obviously more expensive than ripping out tar or other "optional" pieces, reducing unsprung weight from the wheels, tires, suspension, brakes, etc. will make a much more noticeable difference in both power-to-the-ground and suspension behavior. If you're goal is just to improve the handling of the car, some new springs/shocks should do that without making your car any louder and/or unsafe for occupants.
(Also, I think anybody who has had an accident with "lightweight" bumper beams will tell you to stay away from them!!)
