According To The Seller

This 2016 Porsche Cayman GT4 has 10,800 miles and is finished in GT Silver Metallic over black partial leather upholstery with Alcantara inserts and Platinum stitching. The car was purchased by its current owner two years ago and has been driven 5k miles since. 2,580 option, and the exterior also features optional black supports for the adjustable rear wing along with an aluminum fuel cap. The GT4-specific 20鈥?wheels were originally finished in graphite grey and have since been painted silver. A new set of Michelin Pilot Sport Cup 2 tires were installed approximately 2k miles ago. Suspension alterations include TPC rear end links, custom camber settings, and corner balancing. 7,400 option and are distinguished by large yellow calipers at each corner. Note that the custom license plates are not included. 4,730 918-style carbon fiber bucket seats in addition to yellow seat belts, the Sport Chrono Package, and a fire extinguisher.

A weighted shift knob and custom-installed Passport radar detector are the only interior modifications. 5,700 radar detector install integrates into the rear view mirror as shown in the gallery. The digital odometer currently shows under 10,800 miles. According to the seller, the current owner has added 5k miles in two years, and most modifications were installed within the past 1,500 miles. Behind the rear seats is a 3.8-liter flat-six borrowed from the contemporary Carrera S, which produced 385 horsepower at 7,400 rpm and 309 lb-ft of torque at 4,750 rpm when new. Power is sent to the rear wheels through a 6-speed gearbox and a factory limited-slip differential. A clean over-rev report is depicted in the photo gallery. Performance has been increased with a set of Dundon Motorsports headers, a Dundon Motorsports Pro-Tune optimized for 92 octane fuel, BMC air filters, a DSC Sport V2 controller, and a Cobb AP. An August 2017 dyno run resulted in 368 horsepower and 298 lb-ft of torque at the rear wheels. Included service records date back to new and reportedly cover the aforementioned modifications. A selection can be seen in the gallery below along with a build sheet printout.

In its modern form, radar is the use of radio waves to detect the presence and location of an object. It was first demonstrated in 1904 by Christian Hulsmeyer and developed further a decade later by Nikola Tesla. However, it wasn't first used with airplanes until the World War II era. Radar's usage during the conflict forever altered flight tracking history. While many engineers and scientists throughout the 1930s made advancements, full implementation occurred by the onset of the war. Great Britain installed the Chain Home network designed to identify German aircraft attacking the islands. Radar tracking uses a system of observations using radar waves to simulate a flight pattern. Essentially, the system focuses on a target aircraft and sends a series of radio waves designed to locate the aircraft. This gives a ground-based facility the ability to identify where the vehicle is located. A second signal is sent to determine the new location of the airplane. By simulating the two locations, a path for the vehicle can be ascertained.

This helps the crew of the facility determine the speed and overall patterns of flight for the craft. Additional methods of information gathering are also used to determine flight tracking. Since the earliest days of aircraft technology, radio has been used to communicate between the airplanes and the ground crews. By using a specific format for relaying information, the radio communication can be used to accent the radar information. Modern flight tracking history includes the use of global positioning system (GPS) technology. Developed in the late 1970s by the U.S. GPS was instituted in civilian aircraft in 1983 after a Soviet interceptor shot down a Korean airliner, killing 269 people. The full range of flight tracking capability was established in 1995 and grew quickly since then. Today, nearly every airplane flies with the benefit of GPS technology, drastically changing the quality of flight tracking. Flight tracking history took a dramatic turn in the 21st century with the formation of numerous companies that sponsor websites and applications designed to help both airlines and passengers to track the location of aircraft. Using devices such as mobile cellular phones and other forms of PDAs, people and organizations can determine the exact location of an airplane nearly anywhere in the world. Integrating the different technologies of radar, radio and GPS, the flight location of aircraft can be presented on interactive maps in a variety of software formats. While flight tracking history has changed over the course of time to make analysis of the trips aircraft take more efficient, challenges still befall the industry. For example, severe weather still disrupts the tracking methods in place. As technology improves, however, it is expected that more effective and timely ways to keep track of airplanes will continue to evolve.
