This Made in the USA Aluminum Rear Diffuser will help improve the aerodynamics of your Miata, and it looks absolutely killer. This isn't a full race diffuser that's going to gain you seconds at your local track, but it will provide some aerodynamic advantage while also being street capable.
Weighing in at 9.6 pounds, this diffuser is strong but surprising light. The fins are designed with a curve to help improve clearance for entering/exiting steep driveways. The fit is adjustable to help work around other modifications and dial in the amount that sticks out of the rear of the car. Powder coated satin black for a durable and clean finish.
This will require a basic bumper cut, and removal of the rear factory tow hooks. You can read how to perform the bumper cut here: https://spikedperformance.com/blogs/news/how-to-miata-bumper-cut
Works with most aftermarket exhausts that use the factory muffler location. Some exhausts may require modification to the diffuser or exhaust mounting.
We do not accept returns on this part. Please understand that by making this purchase you are open and willing to make modifications if necessary. Every Miata has a different set up, and we did everything we could to make this piece as adjustable and universal as possible. If you do run into an issue and need advice, please reach out.
