Stock springs, strange adjustable shocks, strange adjustable struts, and a GOOD set of lower control arms (ie global west, metco, MM, etc) If you want to get into more money look into double adjustable uppers and even perhaps lowers if you run a LARGE tire.
Even with these, on "street" tires don't expect too much. A good driver should be able to pull 2.0's regularly with relatively little to no mods, so practice, practice, practice as that will yield your best results. Also, get a set of sticky tires, they will more than likely be your best bet for dropping your 60's.
