Most say they didnt like their job if they dont go at least 1.5 inches and I wouldnt go over that else you start to run into issues if not a little at 1.5 inches anyway (lifting the car on jack stands, on car lifts, scraping, etc)
If you want to do it RIGHT then look into H&R springs with maximum motorsport's CC plates (4 bolt design) along with new struts/shocks (brand dependent on how much you have to pay)
The springs and CC plates are KEY but its a great idea to upgrade the shocks/struts while at it. The install is pretty darn easy, we have a how to on the forums you can read over (it has pictures as well)
