High-Performance Subframe Brace – Engineered for Precision

Upgrade your Miata’s subframe with our high-performance subframe brace. Here’s what makes it stand out:

  • Superior Durability: CNC machined from 10mm thick aluminum billet for exceptional strength.
  • Unmatched Rigidity: Attaches to 8 mounting points for maximum stability.
  • Unique Design: Sandwiches the subframe with the brace on one side and stiffening plates on the other for enhanced stiffness.
  • Customizable Fit: Designed to accommodate exhaust systems as large as 3 inches.

Fits NA and NB Miata Models

Our subframe brace comes in two models to fit both NA and NB Miata subframes:

  • NA6/NB Model: Fits all NA Miatas without a factory subframe brace, as well as NB models with a factory brace. If your NA Miata has a factory brace, this option requires cutting off the mounting tabs. If you’d rather not cut, choose the NA8 model.
  • NA8 Model: Specifically designed for NA Miatas with a factory brace. Requires minimal hand grinding for a perfect fit—no power tools needed. This option allows you to maintain the factory brace without major modifications.

Lightweight and Complete Package

Despite its durability, this subframe brace weighs only around 1600 grams, including stiffening plates, spacers, and all necessary installation hardware.

Easy Installation with Printable Template

Before shipping, we provide a printable template to ensure the perfect fit with your car and various exhaust systems. To get this template without ordering, simply contact us. We’ll send you the template and detailed instructions.
