The Benefits of a Front Lip Spoiler

Before we dive into the installation process, let’s briefly discuss the benefits of adding a front lip spoiler to your Miata. The primary advantage of this modification is the enhanced aerodynamics it offers.

A front lip spoiler, also known as an air dam, is a component attached to the underside of a car’s front bumper. Its primary function is to reduce the amount of air going underneath the vehicle. By doing so, it helps reduce lift and increase downforce, resulting in better handling and stability at high speeds. Moreover, since it directs the air around the sides and top of the car, it also reduces drag, which can lead to improved fuel efficiency.

In addition to its performance benefits, a front lip spoiler also adds a visual enhancement to your Miata. It gives the car a lower, more aggressive stance, and can often be painted or finished to match the car’s existing color scheme, creating an appealing, cohesive look.

Tools and Materials You Will Need

Before you begin the installation process, it’s important to gather all the necessary tools and materials. This preparation will ensure a smooth and efficient installation process.

You will need:

  • Front lip spoiler designed for your specific Miata model
  • Drill and bits
  • Screwdriver
  • Wrench set
  • Double-sided automotive tape
  • Alcohol wipes

It’s important to note that the tools may vary depending on the specific front lip spoiler model you’ve chosen. Be sure to thoroughly read the installation instructions that come with your spoiler to ensure you have everything necessary for the job.

Preparing Your Car for the Installation

Before installing the front lip spoiler on your Miata, there are a few preparatory steps to ensure a successful installation.

Start by cleaning the area where the spoiler will be attached. Use a mild soap and water solution to thoroughly clean the underside of the front bumper. Once it’s clean, use the alcohol wipes to remove any residual grease or oil. This preparation ensures the double-sided automotive tape adheres properly, creating a secure bond between the lip spoiler and the bumper.

Next, you’ll need to position the lip spoiler against the front bumper to determine the exact placement. It’s crucial to get this right as it will affect both the performance benefits and the aesthetic appeal of the spoiler. Use masking tape to temporarily hold the spoiler in place and adjust as necessary until you’re satisfied with its position.

Installing the Front Lip Spoiler

Now, you’re ready to install the front lip spoiler on your Miata. Start by applying the double-sided automotive tape to the areas of the lip spoiler that will be in contact with the front bumper.

Next, carefully position the spoiler in place, ensuring it aligns with the markings you made earlier. Apply firm pressure to the spoiler to ensure the tape adheres correctly.

Once the spoiler is secured with the tape, it’s time to permanently attach it. Use a drill to make holes through the spoiler’s mounting points into the bumper. Be cautious not to drill too deep and damage any components behind the bumper.

Once the holes are drilled, use the screws provided with the spoiler to secure it in place. Tighten the screws with a screwdriver until the spoiler is firmly attached. Check the spoiler’s stability by gently tugging on it – if it feels secure and doesn’t move, you’ve successfully installed your front lip spoiler!

Post-Installation Tips

After installing the front lip spoiler on your Miata, there are a few post-installation tips to keep in mind.

Firstly, avoid high-speed driving for the first 24 hours after installation. This allows the adhesive on the tape to cure and create the strongest possible bond.

Secondly, while the front lip spoiler is robust, it’s also the lowest point on your car. Therefore, it’s essential to be mindful of obstacles, particularly when parking or driving over speed bumps, to avoid damaging the spoiler.

Lastly, regular maintenance is key to preserving the appearance and performance of your front lip spoiler. Clean it regularly to remove road debris and check for any signs of damage or wear that could impact its effectiveness.

By following this guide, you can enhance your Miata’s performance and aesthetics with a front lip spoiler. Remember, the key to a successful installation lies in careful preparation, precise measurements, and a little patience. Happy driving!

Understanding the Different Types of Front Lip Spoilers

Before diving into the purchase of a front lip spoiler, it’s essential to explore the different types available to find the perfect match for your Mazda Miata MX-5. The type of spoiler you select will depend on your budget, the look you desire, and the level of performance improvement you seek.

Universal front lip spoilers are a budget-friendly option and are designed to fit a variety of car models. However, as they are not specifically designed for the Miata, they may not provide the best fit or aerodynamic improvement.

Custom-fit front lip spoilers are designed specifically for certain car models. For the Miata MX-5, many manufacturers offer custom-fit spoilers that guarantee a perfect fit and optimal aerodynamic improvement.

Carbon fiber spoilers are the most expensive but offer superior quality and performance. They are extremely lightweight and durable, providing maximum downforce without adding unnecessary weight to the vehicle.

Lastly, there are splitter spoilers, which come with additional rods for increased stability and performance. These spoilers are often used in professional racing and are ideal if you aspire for a track-ready Miata.

How a Front Lip Spoiler Affects the Performance and Fuel Efficiency

Adding a front lip spoiler to your Miata is not just about aesthetics; it also has tangible effects on your car’s performance and fuel efficiency.

A well-placed front lip spoiler can significantly reduce air resistance, or drag, which your car experiences when moving at high speeds. By directing airflow around the car rather than underneath, the spoiler can make your car more aerodynamically efficient. This enhanced aerodynamics translates to increased high-speed stability and improved cornering capabilities.

Moreover, reducing air resistance can also result in better fuel efficiency. With less drag, your engine doesn’t have to work as hard to maintain speed, leading to reduced fuel consumption. However, keep in mind that the improvement in fuel efficiency may not be significant and will also depend on your driving habits and conditions.


Installing a front lip spoiler on your Mazda Miata MX-5 is a worthwhile investment for both aesthetic and performance upgrades. Not only does it give your car a sportier look, but it also improves aerodynamics, leading to better handling, increased stability, and potentially improved fuel efficiency.

From understanding the different types of front lip spoilers to knowing how to properly install one, we hope this guide has provided you with valuable insights. Remember, the key to successful installation is careful preparation and patience. But, once installed, the front lip spoiler will undoubtedly add a new level of appeal and performance to your Miata. Whether you’re cruising down the highway or tackling tight corners on a winding road, you’ll appreciate the enhanced driving experience offered by this modification. Enjoy your upgraded ride!
