How to Fit a Wind Deflector on a Mazda MX-5 ND — Step by Step Guide

Fitting a wind deflector to a Mazda MX-5 ND is one of the simplest modifications you can make to the car. A correctly designed deflector requires no tools, no drilling and no modifications to the vehicle. The whole process takes under five minutes and is fully reversible.

In this guide we walk through the fitting process step by step, along with some tips on getting the best results.

What You Will Need

For a correctly designed ND wind deflector — nothing. No tools, no adhesives, no fixings beyond those that come with the deflector itself. If the product you have purchased requires tools or drilling, it has not been designed specifically for the ND.

Before You Start

Before fitting your wind deflector, it is worth giving the mounting area a quick clean. The area behind the seats where the brackets locate can accumulate dust and debris over time. A quick wipe with a microfibre cloth ensures a clean, secure fit and avoids any risk of scratching the surrounding trim.

It is also worth removing the protective film from the acrylic panel before fitting if one is present. Fitting with the film on will not cause any damage but removing it first gives you a better view of the finished result.

Bracket Orientation — Read This First

This is the single most important thing to get right. Your wind deflector must be fitted with the patterned hex section of the brackets facing the REAR of the car. If the hex section faces forward, the deflector will lean forward and will not sit evenly between the seats. With the hex section facing rearward, the mounting pegs align correctly and the deflector sits flush and upright. Always check this orientation before clipping the deflector into place.

Step One — Locate the Mounting Points

The MX-5 ND has dedicated mounting points located on the top of the roll hoops, directly behind each seat. These are the same points used by the OEM wind deflector if your car came with one from the factory. They are designed to accept the brackets of a correctly specified wind deflector without any modification.

Familiarise yourself with these mounting points before starting — they are the key to a clean, secure fit.

Step Two — Position the Deflector

Hold the deflector horizontally behind the seats and align the brackets with the mounting points on each roll hoop. Check the patterned hex section of the brackets is facing the rear of the car. The deflector should sit naturally at the correct height — it should not require force or adjustment to reach the mounting points.

If the deflector does not reach the mounting points comfortably, or if it requires significant force to align, double check that you have a deflector designed specifically for the ND rather than a generic alternative.

Step Three — Clip Into Place

With the brackets aligned with the mounting points, apply gentle downward pressure to clip the brackets into place. You should feel and hear a positive click as each bracket engages. Do not force it — if the brackets do not clip in cleanly, check the alignment and try again.

Once both brackets are clipped in, the deflector should feel solid and secure with no movement or rattle.

Step Four — Check the Fit

Once fitted, check that the deflector sits level and flush between the seats. It should sit upright and not lean forward or to one side. If it leans forward, check the bracket orientation — the hex section should face the rear. Check that both brackets are fully engaged by gently trying to lift the deflector — it should hold firmly in place.

Sit in the driver's seat and check your rear view mirror. With a quality acrylic deflector, your rear visibility should be largely unaffected — you should be able to see clearly through the panel.

Removing the Wind Deflector

Removing the deflector is as simple as fitting it. Grip the deflector firmly and apply upward pressure to disengage the brackets from the mounting points. The deflector should release cleanly without requiring tools or significant force.

This makes it straightforward to remove the deflector when you need to fold the soft top completely flat, or when storing the car for a period.

Care and Maintenance

Acrylic wind deflectors are easy to maintain. Clean with a soft microfibre cloth and warm, slightly soapy water. Avoid abrasive cloths or harsh chemical cleaners — these can cause fine scratches in the acrylic surface over time.

A plastic polish such as Meguiar's PlastX can be used occasionally to maintain the clarity of the panel and remove any fine surface marks. Apply sparingly with a soft cloth and buff to a clear finish.

Avoid using ammonia-based glass cleaners on acrylic — these can cause crazing and cloudiness over time.

Summary

Fitting a wind deflector to the MX-5 ND is genuinely straightforward when the product is correctly designed for the car. No tools, no drilling, no permanent modification — just a clean clip-in fit that takes minutes and makes a significant difference to the open-top driving experience. Just remember — patterned hex section facing the rear.

Roadster Concept wind deflectors are designed exclusively for the Mazda MX-5 ND and clip directly into the existing mounting points in minutes. No tools required. Made in the UK.
