Using the Eibach Pro - Kit is straightforward. First, make sure your vehicle is parked on a flat and stable surface. It's best to have a professional mechanic install the kit, as improper installation can lead to issues. Before installation, check all the components of the kit for any signs of damage. Once installed, take your car for a short test drive and pay attention to how it handles. When it comes to maintenance, regularly inspect the suspension parts for wear and tear. Check for loose bolts and make sure all connections are secure. If you notice any abnormal noises or handling problems, have your suspension checked immediately. Keep your Pro - Kit clean to prevent dirt and debris from causing premature wear.
