Sounds like posssible alignment and/or geometry issues. Possibly some bump steer as well.

Simple things first, you could simply have a toe out condition at the front.
Front wheels should have a small amount of toe-in, or at least be at 0 toe. Toe-out at the front can help the car turn in quicker, but it also makes the front end very nervous as you describe.

What is your castor setting at the front?
what is your KPI and scrub radius? What offset are the front wheels?

How did you set up the steering rack, and was it checked for bump steer?

Also, are the settings equal side-to-side? sometimes one side can be out and make the front a disaster.

Thats what i would check first if I were setting up a track car. Same for the road.

Hope it helps
Eric
