Using this package is quite straightforward. First, make sure your car is on a flat and stable surface. You can start by removing the old rear control arms and toe arms carefully. Then, install the new adjustable control arms and toe arms included in the package. You can adjust the camber using the rear control arms and the toe using the adjustable toe arms according to your needs. For maintenance, regularly check the powder - coat finish for any signs of chipping or damage. If you notice any issues, you can touch up the coating to prevent rust. Also, inspect the polyurethane bushings and heavy - duty ball joints. If they show excessive wear, it's a good idea to replace them. And always remember to follow the general safety precautions when working on your car, like wearing proper safety gear and using the right tools.
