We’ve spent over 7 years developing and testing the ultimate MX-5 rear subframe upgrade for NA & NB Miata chassis. This is the most versatile rear subframe upgrade on the market.
Take your Miata's stiffening to the next level. Our chassis braces are designed to maximize chassis rigidity by increasing the torsion stiffness of the chassis.
We’ve spent thousands of hours on R&D and real-world testing to bring you industry-leading Mazda MX5 & RX8 performance race parts, engine swaps, and brake kits. All V8R products are relentlessly tested and engineered to perform.
