Never a good idea to learn on the hardest setting.

If its a dry day find the mid point of each unit by counting the clicks forward and backward and start off by setting the front in the middle and the backs 2 clicks soft of middle.

If the back tries to push on in the corners try things like a softer tyre compound or lower tyre pressures or even disconnecting the rear ARB before going harder.

Just go out and have fun - the learning comes with practice and knowing what you want
