Asuming your driving line through the corner is correct.

Change only one setting at a time in small increments

From more to less influence

• Increase front ride height
• Decrease rear ride height
• Decrease rear anti-rollbar stiffness
• Decrease rear spring stiffness
• Decrease rear slow bump and front rebound damper stiffness
• Decrease differential power locking
• Decrease differential pre-load

Generally if a car is oversteering out of a corner the weight is not shifted enough or the transition takes too long over to the rear of the car. To counter that, the rake of the ride height can be decreased or the rear suspension softened to allow the weight shift rearward quicker. Additionally by decreasing the differential power locking and/or pre-load can help with keeping the rotation in control out of a corner.
