Choosing the Right Roof Bars
Roof bars come in two parts: the bar (aluminium or steel) and vehicle-specific feet that bolt to your roof. The right combination depends on your car's roof profile - flush rails, raised rails, fix-points or naked roof.
Bar Types
Aluminium bars are lighter and quieter; steel is cheaper but heavier. Aero-shaped aluminium reduces wind noise dramatically and saves a measurable amount of fuel.
Vehicle Fit
Always start by identifying your roof type. Use the manufacturer's vehicle finder to confirm fit before ordering - feet that don't match the roof type won't be safe to use.
Frequently Asked Questions
How do I know which roof bars fit my car?
Use the manufacturer's vehicle finder (Thule, Mont Blanc, Summit). Enter your make, model and year and you'll get a list of compatible bars and feet for your roof type.
Aluminium or steel?
Aluminium for lower wind noise, lighter weight and longer life. Steel for budget builds and heavy commercial use.
How much can I carry on roof bars?
Most cars are rated 75-100kg dynamic load (while driving). Always check your vehicle handbook - exceeding the dynamic load damages the roof and invalidates insurance.
Do roof bars affect fuel economy?
Yes - empty bars cost about 1-3 mpg; bars with a roof box can cost 5-10 mpg. Aero-shaped bars reduce this. Remove bars when not in use to save fuel.
