What Are Roof Bars And Racks?
Roof bars are fitted onto the roof of a car to securely transport large or heavy luggage, that is unable to fit into the car itself. It could be a bicycle or camping gear, which then can be transported easily. They are also incredibly useful for freeing up space on the back seat or in the boot on long trips.
Roof bars come with different fittings, sizes and materials, each of which are designed to carry specific weights and equipment.
Roof Bar Types
Most cars will fit one of the three main types of roof bar:
- Square bars – the most common type of roof bar, made from steel.
- Aero bars – made from light aluminium. More aerodynamic than other roof bars. T-track system ensures full width of the aero bars can be utilised.
- Thule wing bars – exclusive to the Thule brand. Made from aluminium. Utilise a t-track system and more aerodynamic than square bars.
Which Roof Bars Are Best For My Car?
As we mentioned in the intro, our registration search tool can help cut out the search time needed to find roof bars suitable for your car model. However, to make the most informed decision for you, it’s useful to understand the different specifications you may need to consider.
Car Roof Rail Type
Cars often have one of four types of roof rail:
- Bare roof – no rails or fixed points of attachment
- Fixed points – car has no side rails, but has removable or sliding tabs that conceal a screw hole
- Closed or flush rail – rails run along the length of the car roof
- Open or raised rail – similar to closed or flushed rails, except a gap between the rail and the roof of the car
By knowing what roof rail system your car has, you can determine which type of roof bar and rack you need.
Weight Limits
Roof bars and racks have their own weight limits. These determine their maximum carry weight. You need to consider the weight of what you are hoping to transport. Then, see if it will be too heavy to carry on a particular roof bar rack (most roof bars range from 50kg to 100kg).
As you will also need to consider the weight of the bars and the load, it is advisable to check your vehicle’s manual. This will contain the maximum weight your vehicle can safely carry with a roof rack.
Budget
Steel roof bars can be cheaper than the aluminium variants. So, consider your budget when purchasing a roof rack. Aluminium bars are more expensive, but they can be wider and lighter.
Aerodynamics
Each type of roof bar cuts through the air differently. Steel roof bars are less aerodynamic than aluminium aero or Thule racks, so they may make slightly more noise during your journey. But steel racks can be stronger, meaning they may be more suitable for heavier loads.
Fuel Economy
Due to having a lower surface area and less drag, many roof bars and racks can have a minimal effect on fuel consumption. This will be useful if you need to keep the roof bars on your car for longer periods.
This is not to say no effects will be had. Any change to your car’s shape will affect drag and how hard your car works. Heavier loads will push the car to use more fuel to accelerate.
How To Fit Roof Bars And Racks
Roof bars often come in three parts: the bars, foot packs and a fitting kit. Connect the foot packs to the bars. Then use the fitting kit to attach the foot packs to the car roof. Some car models can come pre-installed with raised roof rails; if this is the case, you may not require a fitting kit.
The instructions that come with your roof bars will advise how much torque to apply to the roof bolts. Make sure not to overtighten them, as this may damage the rack and your car.
Leaving Roof Bars On Your Car
Roof bars and racks are constructed with durability in mind, so leaving them on your car long-term is an option. On the other hand, changes in weather will eventually wear them down. For this reason, it is advisable to remove roof bars and racks if they are not being used, to avoid them becoming oxidised and worn down.
