The Purpose of a Convertible Wind Deflector

To determine what really makes a wind deflector good, we first need to outline its benefits.

When your vehicle moves forward, an airflow is created. The wind flows over the hood and windshield of the car and returns toward the cabin via the rear. Especially at higher speeds, wind turbulence increases. A good convertible wind deflector reduces the turbulent air caused by driving with the roof down. A wind deflector captures this airflow, helping to prevent a stiff neck and messy hair. Your convertible drive becomes quieter and more comfortable, and with a good wind deflector you can even drive with the roof down at lower temperatures.

A wind deflector is designed to disrupt airflow, not to block it completely. The airflow is redirected, resulting in a more pleasant drive, less noise, and reduced cold while driving with the roof open.

Wind Deflector Mesh Material

The mesh is the most important component of a wind deflector. The type of mesh used has a major impact on the effectiveness of the deflector. A good wind mesh has a weight of 50g/m² and a mesh size of 1mm. For example, chicken wire barely blocks any wind at all.

The right material ensures wind and noise reduction of up to 80%. By using 100% polyester wind mesh, the mesh can stretch slightly, allowing it to capture the wind optimally. It is important that air can pass through the mesh and be slowed down in the process. A fully closed wind deflector, or one with a mesh size that is too small, can cause the deflector to vibrate.

Fitment of the Convertible Wind Deflector

Fitment is, of course, another important aspect when comparing different suppliers. You are looking for a wind deflector that fits neatly. A poorly fitting wind deflector can be distracting while driving, as it may rattle or function insufficiently, reducing too little wind and rendering the deflector ineffective.

What should you pay attention to when comparing?

For example, you can ask yourself the following questions:

1. Can the convertible roof be opened with the wind deflector in place?
2. Does the wind deflector fit neatly along the interior?
3. Does the wind deflector use original factory mounting points?
4. Does the mounting secure the wind deflector firmly within the interior, with minimal play?

Mounting in the Convertible

How is a wind deflector mounted? This differs per type of convertible, and within these mounting types there are also various designs available on the market. Consider differences in quality, application, and finish. The difficulty of installation is also important. Does the supplier provide clear instructions? How long does installation take? Can installation be done by one person? These are all questions that help determine whether you have the right wind deflector.

In many cases, the type of mounting is determined by the car manufacturer. Many classic convertibles use a holder system, such as the Mercedes W113 Pagoda. Other brands feature a ready-made clamping system, such as modern BMW models. Finally, there are convertibles that use a combination of a clamping system and a holder system.

Different mounting methods:

1. Velcro straps around roll bars.
2. Click system with sliding pins (is your cabrio already equipped with mounting caps?).
3. Holder system.
4. Tension strap system.
5. A combination of the above.

It is therefore important that the mounting system seamlessly matches the system used by the car manufacturer. If it is not perfectly adapted, there is a risk that the wind deflector may damage the interior or shift and rattle while driving.

Finish of the Wind Deflector

The finish of a wind deflector often reveals its quality and is also the first thing you notice when comparing wind deflectors. The quality, craftsmanship, and materials used are clearly visible to the naked eye. The actual performance, however, is something you will experience while driving.

You are looking for a high-quality finish that matches the interior of your convertible. Consider the materials used, stitching, color, and thickness. A premium wind deflector is neatly finished, features strong (double) stitching, has no protruding parts, and is made from materials of the same quality (and color) as your interior.
