context_page_description: The Porsche 962 is a sports-prototype racing car built by Porsche as a replacement for the 956 and designed mainly to comply with IMSA's GTP regulations, although it would later compete in the European Group C formula as the 956 had. The 962 was introduced at the end of 1984, from which it quickly became successful through private owners while having a remarkably long-lived career, with some examples still proving competitive into the mid-1990s. The vehicle was later replaced by the Porsche WSC-95.
context_section_description: Beyond minor modification, some private teams reengineered the entire car. One noted problem of the 962 was a lack of stiffness in the aluminium chassis, which lead some teams to design a new chassis, and then buy components from Porsche to complete the car. Some custom cars also had unique bodywork. Some teams would then offer their 962s to other customer teams.
  Among the most popular privately built 962s was that from Kremer Racing, named the "962CK6, which did away with the original aluminium sheet tub of the original Porsche chassis, replacing it with a carbon fibre tub. Eleven chassis were built, campaigned by Kremer and other teams. John Thompson designed a chassis for Brun Motorsport, eight of which were built and helped the team take second in the World Sportscar Championship in 1987. Thompson would later build two chassis for Obermaier Racing. Richard Lloyd Racing's GTI Engineering would turn to Peter Stevens and Nigel Stroud to develop five 962C GTis, which featured entirely revised aero and aluminium honeycomb rather than sheet tubs. Former factory Porsche driver Vern Schuppan would also build five new chassis, some known as "TS962s".
  In the United States, the ball got rolling when Holbert Racing began making modifications to their own chassis and rebadging them with "962 HR-" serial numbers. The search was always on for a stiffer and safer 962 monocoque and Jim Busby contracted Jim Chapman to build a more robust version of the 962 monocoque. Fabcar would become the de facto factory tub supplier, supplying chassis with official Porsche serial numbers. Fabcar incorporated changes to the factory tub, replacing the simple sheet aluminum construction with a combination of sheet aluminum and aluminum honeycomb in addition to billet aluminum bulkheads. These changes substantially increased the tub's crashworthiness and stiffness. Dyson Racing purchased a Richard Lloyd Racing / GTi Engineering 962 monocoque for use in their Porsche 962 DR-1 chassis. A Fabcar tub was used in Dyson's Porsche 962 DR-2.
  Some 962s were even more extensively modified, with several open-cockpit versions being developed in the mid-1990s to run under new sportscar regulations. Kevin Jeanette built the Gunnar 966, mimicking elements from the 917/30 Can-Am cars. Kremer Racing would once again develop their own chassis, with the open-cockpit CK7 running in Interserie and K8 running at most international sportscar races, including Le Mans and Daytona. These cars shared little with the original 962s, using custom bodywork and chassis designs, yet retaining the engine and some suspension elements. Heinz-Jörgen Dahmen converted his 962 (chassis 011) to an open-top version that he raced in the Interserie in 1995 and 1996. The car had previously been campaigned by him in the Interserie since 1990.
