I'm actually originally from Dundalk and I go there quite often to visit family still... BUT my tools and the garage I use is 2 hours away in WV. I've lowered cars before just parked on the side of the road but its always easier with a garage w/compressed air.
Unless you plan on hauling around a ton of rocks or something and dumping the car real low, it probably won't make much of a difference. Either way, the stock shocks will wear out faster with shorter springs.
well im asking because some weekends i taxi my daughter and her friends around. on some occasions i have 5 people in my car and its gets pretty heavy n the back seats.
