Tokico makes a very nice spring/shock combo kit for the 2G, Enes has it and seems very happy with it. Plus the drop looks really nice.

If you want coilovers, Tein makes some very nice setups, but stay away from JIC. Also, avoid the cheap eBay coilovers. I used to have GroundControls but really don't recomend them to anyone.
