To our dedicated patrons and newest customers, Join us in celebrating our 45th Anniversary! Our website showcases the newest and most innovative performance parts in our industry.

The Neumann Family started Automotive Performance Systems, Inc. in 1975, with an ambition to offer the best, highest quality performance parts and provide the most dedicated customer service. Today we are still working hard to meet your needs and exceed your expectations in defining performance; our total commitment and tradition lives on.

Many aftermarket companies have been bought, sold or have been consolidated with others, while we remain independent and continue to be family owned. Those companies answer to majority owners, board members, or Wall Street – people who usually are not remotely interested in cars.

Automotive Performance Systems, Inc. answers to you - the automotive enthusiast. Our family and our own NEUSPEED® product line will not sacrifice quality to reduce costs. All our parts are designed, engineered, and manufactured with a special pride no longer seen; after all, it’s got our name on it! We continue to pay careful attention to every detail, and we are committed to specialize and build the best products available.

Our website will provide you with the very latest NEUSPEED® parts and new offerings from high-end companies that complement our products. You will also find the newest parts from our long-time partners Bilstein and Koni. You can be assured that we have tested and approved every new part before they are offered for sale.
