Jamie,
If you running up at Fredrick, I'm assuming your using a one-way. Have you tried a simple spring/droop change? Also, you can use alittle more toe to get steering out of the corners. You also might want to try changing the ackerman. If the car is still out to lunch, you might wanna get ahold of Brian Riegal. He had the car for a while and had it dialed at the "C".
