I found this article that longtime 99er Dave Clement's daughter Samantha 
wrote for the San Joaquin Delta College newspaper. If you want to read  and 
look at 99 Speedway's long history, click

Fifty-year-old speedway still 
brings a crowd to the stadium
  At the end of World War II, the sport of auto racing started to become 
  increasingly popular and the idea of having a race track inside Stockton's 
  city limits was in the mind of William G. Hunefeld. 
  After living in New York and then traveling across the United States living in 
  various states, Hunefeld eventually settled in the Stockton area, promoting 
  his boxing and wrestling business.
  With the help of Stanley S. Moore and lawyer Len H. Honey, the construction of 
  a fifth-mile dirt racing surface was started in March of 1947 and completed in 
  May of the same year.
  The new 99 Stadium, as it was called, featured grandstands on both sides of 
  the track, which provided seating for 10,000 people. The back stretch 
  grandstands were removed a few years later to make room for Moore's truck and 
  recreational vehicle buildings.
  The inaugural race was held Tuesday, May 27, 1947, featuring a 12-car field of 
  Midgets under the sanction of the United States Racing Association. A crowd of 
  more than 8,000 was on hand for that race.
  Throughout the years the Stockton 99 Speedway has seen more than 15 different 
  divisions competing on the quarter-mile asphalt track and in the 1950s, NASCAR 
  took them on to be a sanction track.
  In 1985, Johnny Brazil drove his Super Modified around the quarter-mile track 
  in an amazing 11.899 seconds. To this day, he is still the fastest man ever to 
  circle that track.
  In 2000 the Super Modified division returned for a one-time show and tried to 
  break Brazil's record but Lonnie Anderson, from Salt Lake City, Utah, only 
  reached 11.926 seconds.
  Brazil walked away from the fence smiling and said, "They didn't touch it."
  Currently, after 55 years of racing, the track has three regular divisions, 
  along with a hand full of other divisions that participate on any given 
  Saturday night.
  The season ends in late September leaving only three races for the season.
  Tomorrow's program will feature the SLR tour-style cars, similar to ones shown 
  on television, and the Legends, along with the tracks regular divisions, the 
  Western Late Models, Grand American Modified and the Pure Stocks.
  As the season draws to a close, the points season ends with some battles, 
  while for others, it is another mark on the victory list. 
  In the Pure Stock division the Rookie of the Year honor will go to David Ball, 
  who is also a student at Delta College.
  Ball is working towards his certificate in diesel automotive.
  "I never was really working towards being Rookie of the Year, I was just out 
  having fun," he said.
  Ball has nine top-10 finishes, a B-Main event win and two heat race wins.
