Seyfer Automotive Performance Services

Seyfer Automotive specializes in delivering the balanced package in performance cars. It is our belief that a vehicle that is just fast is not responsible or safe for the enthusiast. We recommend balance between the critical elements a vehicle must deliver, namely: as much torque as your pocket book will buy, razor sharp handling and gravity defying stops. All of these elements are available to the enthusiast today. In fact, it is possible to make a 50’s or 60’s car, or muscle car, deliver the kind of performance previously available only in cars that cost far north of the $150,000 range. And, if you are a fan of American sport compact or truck performance, Seyfer can provide you with the same balanced approach allowing your vehicle to be custom tailored to your exact needs and desires.

We combine the use of various computer software applications with our 40 years experience to create successful street engines. We map and revise suspension pick-up points for better handling, improve braking performance, and create better launch traction, by way of improved geometry and suspension design. Amazing performance can be yours in almost any vehicle. We have a 1955 Ford station wagon that can carve the canyons at nearly double the speed limit and stop like a race car, all on a comfortable air suspension system.

If you demand that your vehicle provides comfort along with performance we can provide everything, from custom hidden stereo and CD sound systems that will not affect the “look” of your vintage vehicle, to complete integration of late model body controls, including power windows and locks, cruise control, power steering, computer controlled air suspension or most anything else you desire. We routinely work with AutoWeave Upholstery to create comfortable and user friendly vehicle environments that can keep out the heat and noise of high performance engines. We are able to model new components or additions to your interior in clay, and take the design to a finished fiberglass version that can be painted or upholstered to tastefully integrate into your vehicle. Our technicians are ASE certified in electrical, suspension and steering, engine performance and repair, transmissions, drive train, heating and air conditioning and brake systems. It is very rare to find a hot rod shop with ASE Certified Master Technicians, but due to our experience in the repair and maintenance of late model vehicles, we can also bring this discipline to your hot rod project.

If you are into late model performance, Seyfer can offer everything from one-off customs like our V8 Focus that is completely emissions legal, and offers our famous balance in a range that many super cars cannot achieve. For owners looking for more towing power or street horsepower, we have options that run from supercharging to better exhaust and everything in between. Please give Donny a call at (303) 422-5261 with any project large or small, and let’s talk about how we can make your dream car a reality.
