True, but it also lowers the center of gravity pretty significantly by taking a large sum of weight off of the highest point of the car, while only slightly decreasing traction with an increase in acceleration due to the weight loss. As opposed to a horsepower increase which will much more significantly reduce the rear wheel grip during low speed acceleration.
