Welcome to HS
Since you're going for show, you'll want to save up for wheels and a drop right away. You'll want adjustable springs for show so you can slam it when you want to. Look into a Ground control/Koni yellow setup for ~$850 or so. If you want to spend a little more, you could get true coilovers, or if you want to spend less, you could get non-adjustable springs. Its up to you.
