Handling in corners

I race my 94 eclipse at the local dirt track in West Liberty, Iowa. I have a fast car on the straight away and back stretch, but I seem to lose Horsepower in the corners. Any suggestions on what I can do to the car to help me through the corners better? Setups? Springs? Anything. Make it a cheap way, racing makes me not have left over money. I do have a 2" spring rubber in the right front, but sometimes that makes me push up the track.
