Both the chests and the roof racks are designed to solve space problems when traveling with bulky luggage, such as the bicycle or the necessary material for a vacation. In these cases is when roof racks and luggage racks are an option to consider, especially if the space problems are occasional and we do not want to change the car for a bigger one.
The roof chests are a perfect solution for space problems in all types of cars. They make much more use of trips as they increase the luggage space. Unlike the roof racks, the chests are more aerodynamic, although they do not offer as much flexibility when loading the luggage.
The roof racks , on the other hand, offer more flexibility, since they do not have a limited capacity. A roof rack consists of two bars, one front and one that goes in the back of the car. Each has two couplers located on the sides that serve to fix the roof rack to the roof of the vehicle. When choosing the roof rack, the width must be taken into account and the bars must be long to cover the car. In addition, the couplers must be compatible with the fasteners.
On the other hand, the roof racks are recommended if there is little load and it is not very bulky. Otherwise, both the stability of the car and the aerodynamics would be affected by excess volume.
