About AMS Performance:
At AMS Performance, we specialize in automotive performance for turbocharged vehicles. In addition to being a leader in the automotive performance parts manufacturing industry, we offer in-house engine computer calibration, parts and package installations, as well as engine and transmission building services.

First and foremost, AMS is an engineering company. Unlike many shops, our parts are engineered to be the best performing components you can buy. It is common for many manufacturers in the industry to have a basic understanding of engine performance, but at AMS we take it far past that using computer-aided designs and mechanical engineers with years of motorsports experience.

AMS Performance has been at the top of the game since opening our doors over 20 years ago. From turn-key packages to individual components, we can meet and exceed all kinds of performance goals. From drag racing to road racing, and everything in between, let AMS enhance your driving experience!

Why we love Subiefest Midwest:
We love coming to this event because there is no better place in the country to connect with all the different types of genuine Subaru enthusiasts in one place. We also love having the opportunity to show the community the new parts we've been working on.

Why you should come to our booth at SFMW 2026:
Celebrating 25 years of AMS, we're bringing our newest Subaru parts to the booth, including prototypes you won't see anywhere else yet. Stop by to talk shop with our team about our VB WRX turbo shootout results and see the engineering behind every part up close.
