Hi, over my stock one, I don't think there is a massive up scale, however being all one piece, it will have improved stiffness. Over a vehicle with no brace, there will be a stiffness improvement yes, however it depends what you are doing with the car. If its just a daily drive then you wont really need it, however if you are putting it through its paces through twisties, then definitely, but its worth getting a geo and suspension upgrade too... hope that waffle helps!! hahaha
