I wouldn't worry about understeer. It is safe and you will learn to rotate the car using the throttle. After you learn to drive it the way it is then you can worry about modifying the handling.

Also, playing with the air pressure will also modify the handling at the track. I ran H&R coilovers with stock sway bars and ran well. After four years at the track I finally went with Hotchkis sways; big difference in handling.

You are going to driving school and the stock sways are capable and fun actually. I would leave them for now.
