Are you a proud owner of a Mazda Miata? If so, you might be familiar with the common issue of rocker panel rust. Over time, moisture and road salt can cause the rocker panels to deteriorate and become unsightly. In this article, we will discuss the process of replacing the rocker panels on your Miata and provide you with some useful tips to ensure a successful repair.

Why Replace the Rocker Panels?

The rocker panels not only contribute to the structural integrity of your vehicle but also play a significant role in its aesthetic appeal. Rusty or damaged rocker panels can greatly diminish the overall appearance of your Miata. Additionally, if left unaddressed, the rust can spread and cause more severe damage to other parts of your car. Therefore, it is essential to replace the rocker panels as soon as you notice any signs of rust or deterioration.

Tools and Materials Needed

Before you start the replacement process, make sure you have the following tools and materials:

  • Jack and jack stands
  • Socket set and wrenches
  • Protective eyewear and gloves
  • Grinder or sanding tool
  • Welding machine or adhesive
  • Primer and paint
  • New rocker panels

Gather these items and ensure you have a well-ventilated workspace before proceeding with the repair.

Step-by-Step Guide

Step 1: Elevate and Secure the Vehicle

Start by elevating your Miata using a jack and securing it with jack stands. This will provide you with enough space to work comfortably and safely.

Step 2: Remove the Damaged Rocker Panels

Using a socket set and wrenches, carefully remove the bolts and screws that hold the damaged rocker panels in place. Take your time to ensure you don’t damage any surrounding parts during this process.

Step 3: Clean and Prepare the Area

With the old rocker panels removed, use a grinder or sanding tool to clean the exposed metal surfaces. This will help remove any remaining rust and provide a clean surface for the new rocker panels to adhere to. Once the area is clean, apply a coat of primer to prevent future rusting.

Step 4: Install the New Rocker Panels

Carefully align the new rocker panels with the existing mounting points and secure them in place using bolts or screws. If you’re using an adhesive, follow the manufacturer’s instructions for application and drying time. Ensure the panels are firmly attached and aligned properly.

Step 5: Paint and Finish

Once the new rocker panels are securely in place, it’s time to paint and finish them to match the rest of your Miata. Choose a high-quality automotive paint that matches the original color, and apply it evenly to achieve a seamless look.


Replacing the rocker panels on your Mazda Miata is a worthwhile investment that will enhance both the appearance and structural integrity of your vehicle. By following the step-by-step guide outlined in this article and using the recommended tools and materials, you can successfully complete this repair and enjoy your Miata for years to come.
