Lowering the car changes the suspension geometry. Depending on the design of the suspension, the wheels may or may not tilt in or toe in when the car is lowered. Regardless, any car should be re-aligned after changing springs or shocks. But after adding lowered suspension parts, the car may not be able to get back into stock alignment rage. That's where aftermarket camber hardware comes in.

Alignment hardware gives extra adjustability to bring the alignment back into factory specifications. The amount of adjustment needed will depend on how far the car was lowered. For a one-inch lowered car, plus or minus one degree of correction should let the car come back to stock specs. For a car dropped two inches or more, the camber adjustments will need to be more dramatic.

Ignore the alignment effects at your peril. Besides reducing handling effectiveness, bad camber and toe settings can destroy tires in short order, since the tires are moving in a different direction than the direction the car is traveling. If the tire is visibly tilted in, you can bet it is wearing out at a much higher rate than normal.
