I guess it depends on what do you plan on doing with your car, do you want to lower the car for performance or looks. Do you have big wheels? Do you need the option of adjusting the height of your car?
A camber kit generally isn't needed unless you're really dumping your car. If you're doing something like a 2" drop you'll be fine without camber adjusters, unless you're tracking your car.
"Driving is like a narcotic, an addiction that can take over lives. It ruins people, breaks families apart, and even kills. Itís habit that needs to be fueled. Time, money, rationality, sweat, knuckle skin, and anyone who disapproves are of little importance to a driver, and are often overlooked. Hi, Iím Nelson, and Iím a drivaholic."
