Uprated Antiroll bars are a great way if you doing the endlinks and then get a set of coilovers if you want to go all the way
All the way to the end of the budget :-D
Does anything need to be done with the coilovers? Is it only of you drop it by extreme amounts that you need to watch things like camber? [suspension newbie]
Nope, you should be ok if you keep the ride height the same, I droped mine about 2 inchs when I got it and it really through the camber out, went with some cusco camber and toe arms and bought it back in but its now gone back up about 1/2 an inch to save scraping! Worth budgeting for some type of camber arm adjustment.
Amazing difference with droplinks, biger ARB's and coilovers
