There will be some minor improvements, but only when the car is driven hard through the corners, and if you are going to drive the car that hard and especially on public roads, then perhaps, and please don't take this personally, a high performance driving course, or Solo 2 races to improve your driving skills should be your first investment towards the performance improvement of the car.It's never wise to think that adding a couple of performance parts to your car will magically transform the owner into Mario Andretti or Michael Schuemacher, we all like to think we are better driver than the next guy if our cars were better/faster, but the fact of the matter is that most of us are OK drivers at best, and it is really dangerous to falsely think that we can be better with some minor performance parts added to our cars.
