Other than potentially a bit more negative camber on the front and maybe a bit more caster by pushing the subframe as forward as it will go not much really. Rears are best left unless you have lowered the car and fitted adjustable tie bars.
Toe is something you 'could' play with, more positive toe on the front will give a sharper turn in but will also make the front feel more nervous. Its really down to personal preference at that stage.
You can get a little more negative camber out of the front by opening the slots where the ball joint fixes to on the front wishbones, other possible mods that are worth while are Powerflex front bushes for the front wishbones and making sure you have non voided rear bushes in the front wishbone too. These can also be upgraded with vibratechnics bushes which will give a much more solid feel to the front. Don't use Powerflex equivs though as these have been known to squeeze out.
