 From the 901 to the 991 and the 996, failing hood struts are a right of passage for Porsche's 911. Just about every model uses them, so finding that your struts are failing isn't anything unique. As 911 owners know, interior storage space isn't the best compared to a sedan, so trunk use can be...

The condition of the BMW F30 rear brake pads and rotors is critical. Without them, you're a liability to yourself and everyone around you. BMW builds all of its models as performance luxury sedans, and the brakes play a critical part in their development. The single-piston sliding calipers BMW...
