Auto racing (also known as car racing, motor racing or automobile racing) is a sport involving the racing of automobiles for competition. The main aim of an individual event is to set the fastest time in a set number of laps or time limit. The finishing order is determined by race time, with the fastest time in first place, second-fastest in second place and so on. Any driver failing to complete a race for any reason is deemed "retired", or, more commonly, "out". Retired drivers will have their positions determined by the order in which those retired, with the first to retire finishing last, the next second-last and so on. In most events, a driver's final race position may be classified if he/she completes a certain amount of the race distance, usually just short of completing the full race (for example, in Formula One, a driver's race position is classified if he/she completes 90% of the full race distance). There are numerous different categories of auto racing, each with different rules and regulations, such as compulsory pit stops and car regulations, for all cars and drivers to comply. The continuous exposure of a driver to vibration and G forces in years of automobile racing may have a substantial effect on the high incidence of musculoskeletal disorders.
Piper Race Cars is an American racecar constructor. The company was founded by Don Sievenpiper in 1991.
Piper Race Cars was founded in 1991 by Don Sievenpiper. He designed the Piper DF2 to race in Formula Ford 1600 in 1992. The DF2 was followed by the DF3 in 1998. The Piper DF3 won the SCCA National Championship Runoffs in the Formula Ford class in 2010 and 2012 with Tim Kautz. In 2002 the DF3 was replaced by the DF5. Tim Kautz won 2 races in the F1600 Championship Series in Piper DF5 which placed him second in the championship. The Piper DF5 won the Runoffs in 2002 and 2003 in the Formula Ford class with Justin Pritchard. The runoffs were almost won again in 2004, but a bolt in the brakes came undone and the car went flying off the track. After that a Formula 2000 variation was made. In 2007 and 2008 Justin Pritchard won the AARC F1000 race at Road Atlanta, and was winning at another race in 2008 until an engine blow took him out of contention. Don Sievenpiper sold the company in 2007 to Fast Forward Components. In 2011 a Piper DF5 driven by Brian Novak won the SCCA National Championship Runoffs in the Formula 1000 class.
