Too stiff on the front, and it will understeer, too stiff on the rear and it will oversteer. Experiment with the settings so that it handles how YOU like .

Set the ride height so that the rear is 10mm higher than the front. The ride height is set up by the front suspension TCAs, so make sure they are either parrallel with the ground or with the outer TCA joint being fractionally lower than the inner one. Set the rear height to this (+10mm).

Happy now?
