For street driving we're not at the limit, so it's quite common to find adding ballast makes the car feel better. However, generally speaking a lighter car is faster even if you have to drive around a balance issue although it may not be as much fun to drive. That's why pretty much all class racing either limits what you can remove, or sets a minimum but not maximum weight. This is also why people put so much time and effort on the suspension, getting the weight transfer to work the way you want it to leads to better lap times than adding weight.
