the struts you're using under there are a good starting point. I must add at this point your question is a little vague. The reason they are good is the hilux calipers bolt straight on and all you need to do is convert your struts to coil over and you're cruising.
more track could be done with longer control arms. if you're interested in a track junkie and not too worried about how much camber you'll have the sigma CA are long and the cressida ones are even longer but you'll need so sort out different tie-rods etc.
