PPI stood for Precision Preparation, Inc., a company founded by team owner Cal Wells in 1979. The company provided parts for off-road racing teams. Over time, PPI eventually began its own off-road team, with help with Toyota Motorsports. PPI fielded off-road trucks for Mickey Thompson's SCORE series and then later fielded trucks which competed in outdoor events such as the Baja 1000. Notable drivers for PPI include Ivan "Ironman" Stewart and a young Robby Gordon (who also drove in CART for the team in 1998).
