Do you have stock suspension? Good tires, pressure, and alignment make a big difference. Like another member posted, everything you change is a tradeoff.
My car is setup to turn, but it suffers in a straight line at high speed. It picks up all the unevenness on the road. All of my agressive driving is in the 30-60mph range. If I wanted a track car I would have bigger tires and a different alignment.
