The Mazda Miata MX-5 NA is a well-known sports car that has been loved by many since it was first made in 1989. This car is famous for its small size, lightweight design, and amazing handling on the road. Whether you’ve owned a Miata for years or just got one, you may want to upgrade it with the best parts. Using the right Mazda Miata MX-5 NA parts can make your car perform better and look great. In this guide, we'll go over the key parts you can use to improve your Miata and make it last longer.

Benefits of Upgrading Mazda Miata MX-5 NA

Choosing the best parts for Mazda Miata MX-5 NA has many benefits, including:

• Better Performance: Adding parts that improve your car’s speed, handling, and braking makes driving more exciting.

• More Durability: As cars get older, the original parts can wear out. New parts make sure your car stays strong and reliable for longer.

• Improved Looks: The right parts can keep your Miata looking sharp or even make it look cooler than when you first bought it.

• Customization: With aftermarket parts, you can personalize your Miata to fit your style, whether it’s for better speed, comfort, or appearance.

Important Mazda Miata Parts to Consider

When upgrading your Miata, here are some of the most important parts you should know about:

• Billet Throttle Cable Bracket

This part helps if you’re upgrading your Miata to a Skunk2 manifold. It gives you smoother control over the throttle, making driving more precise.

• Goodridge Clutch Line (94-95)

If you have a Miata made between 1994-1995, upgrading to a stainless steel clutch line can improve how your pedal feels. It gives better response and makes driving more enjoyable.

• Mishimoto Aluminum Radiator

This radiator keeps your engine cool, even during long drives or races. It’s a key part if you want your Miata to perform well under pressure.

• Billet Aluminum Alternator and Water Pump Pulley

By replacing the stock pulleys with lightweight aluminum ones, your engine will work more efficiently. This can give your Miata a small boost in performance.

• Flat Underbody Kit (1990-2005)

This part helps make your car more aerodynamic and protects the underside of your Miata. It also improves your car’s stability when driving at high speeds.

Top Miata Parts for Maximum Performance and Rigidity

• NA MX-5 Miata Delrin Door Bushings

Best bang for the buck chassis stiffener mod for your MX-5 Miata! These units replace the stock rubber door bushings on your Miata with solid delrin door bushings. They allow your door to more rigidly connect with the chassis, resulting in a noticeable reduction in chassis flex in corners and going over bumps. Less chassis flex results in your suspension doing the work it was meant to do.

• NA MX-5 Miata Frame Rail Braces

CNC Laser cut and bent out of 304 Stainless Steel, these braces help tie together one of the flimsy weak spots of the Miata's chassis; the "mushy mashed potato" like frame rails. These rails slip over the pre-existing rails and bolt through your floor with stainless steel bolts and lock nuts. We designed our frame rails to not have any cut outs for a more rigid construction. A set of our Frame Rail Braces weigh 15.7lbs. It wasn’t worth saving a couple pounds to sacrifice protection to the frame rails and rigidity.

Advantages of using these frame rail braces include:

1. They serve as a strong place to jack up the car and place your jack stands.
2. Protect the OEM frame rails from speed bumps, race track curbs, or any accidental off-road adventures.
3. Less chassis flex.
4. They fit all NA and NB Miatas. You will be required to drill through your floor to install them. If you are not confident to drill through your car's floor, we recommend that you take it to a licensed mechanic.

Popular Mazda Miata Accessories

• Interior Upgrades: You can swap out your steering wheel, seats, or gear shifter to give the inside of your Miata a personal touch.

• Exterior Styling: Adding spoilers or side skirts can make your Miata stand out while also improving its aerodynamics.

• Lighting: Upgrading to LED headlights or taillights not only makes your car look modern but also improves your visibility at night.

These accessories allow you to make your Miata more stylish and suited to your personality.

Cooling System Upgrades

For Miata owners, adding NA MX-5 Miata Aluminum Hood Vents helps to vent excess heat from under the hood, enhancing airflow and preventing overheating during heavy use. Pair this with the Skunk2 Alpha Series 90-98 Mazda Miata Radiator and Mishimoto 90-97 Mazda Miata Aluminum Fan for maximum cooling efficiency. These components work together to keep the engine cool, especially during hard driving or racing. Overheating can harm the engine, and these upgrades can prevent that, making them essential for anyone pushing their Miata to perform better.

Suspension and Handling Improvements

Skunk2 Mazda Miata NA/NB Pro-ST Coilovers offer adjustable ride height and damping, giving you full control over your car’s performance on both the street and the track. To further enhance handling, install NA/NB MX-5 Miata Frame Rail Braces to reduce chassis flex and protect the frame from damage. Pair these with NA/NB MX-5 Miata Adjustable SwaybarEndlinks to fine-tune the suspension response, helping your car stick to the road better.

Engine Performance Enhancements

For people looking to increase their Miata’s power, parts like the Billet Aluminum Alternator and Water Pump Pulley help reduce the load on the engine. These pulleys are lighter, so the engine doesn’t have to work as hard, freeing up a little more power. This is a simple and effective way to get more performance without spending a lot of money on big modifications.
