Mustang GT S3X built for power, road handling performance, aerodynamic looks and pure desire. Includes a 360 degree radar detection and laser jamming package with two V1 remote radar detectors, blinder m45 laser jammer and laser blinder m25. The Mustang has a long history as a sports car. It has good looks and handles reasonably well. Performance and handling has advanced to a point of providing a highly responsive vehicle in handling, aerodynamic styling and horsepower. Perhaps you are thinking of buying a true sports car and have asked yourself, “which vehicle is best for true performance, looks, handling and suspension”? Our Racing Business Group is focused on this fascination with high performance vehicles. It is what we are about. Building special sports cars with high levels of performance.

The Stage III Xtreme (S3X) is for the driver who wants immediate and responsive horsepower, 650HP+; precise suspension and road handling; vented, aggressive disk brakes; adjustable suspension; additional aerodynamic styling; side exhausts with a deep throaty resonance exiting just in front of the rear wheels. Front and rear hidden radar detectors, front and rear laser jammer countermeasures, photo speed trap alerts are provided with radar alert directional arrows telling you where the radar threats are coming from. Stage III cockpit leather is enhanced with built in lateral G Force support on the two front seats. Improved seating comfort, entry door sill and dash styling improvements are provided. Engine performance gauges and controls are provided.

People will be compelled to admire a S3X Mustang GT as you drive by. It is beautifully styled, comes across as very fast and assertive; ready to launch even when parked! We don’t chrome a sports car out and add components that are not useful. That is for tasteless drivers with a lack of confidence. High performance and aggressive looks is what we are about! The S3X Mustang GT is for confident drivers who know what they are looking for and know it when they see it!

Check out several of our project cars at the bottom of this page for our customers: There is a difference of what we offer as compared to tuner sports car companies, who also offer high performance. Our staff participates in racing Lemans type tracks. One of the staff is NASCAR experienced and a mentor to the younger staff. While most sports car manufacturers focus on quarter mile statistics to provide credibility and performance statistics, we know from experience a sports car has to provide straight line performance; as well as handling on curves, bumps and hills.

The cockpit has to be comfortable with useful instrumentation which is easy to read and control, functional and stylish. We pay attention to driver handling, cockpit aesthetics, suspension, engine power, aerodynamic streamlining, “down force” to the rear wheels as well as “road vacuum” capabilities to hold the Stage 3 XTreme GT close to the road surface at higher speeds. We want your Mustangs to have a fast, panther look - parked in town, in your driveway and while driving in the curves as others drive by. People will be compelled to take that second look to admire the beauty, styling and throaty power of the S3X, which tracks the road beautifully and feels very comfortable when driving around town or on long road trips.

If that is what you are looking for - aggressive, dynamic looks; superb handling; road hugging power at your fingertips; then you have found the company to meet your sports car objectives. A truly superb sports car will compel people to admire the lines and aerodynamics of the vehicle.
