IMSA GT Championship

IMSA GT was a sports car racing series organized by International Motor Sports Association. Races took place primarily in the United States and occasionally in Canada.

History

The series was founded in 1969 by John and Peggy Bishop and Bill France, Sr., and racing debuted in 1971. It was originally aimed at two of FIA's stock car categories running at two different classes, the GT (Group 3 and 4) and Touring (Group 1 and 2) cars. The first race was held at Virginia International Raceway; it was an unexpected hit with both the drivers and a handful of spectators who attended.

For the following year, IMSA founder John Bishop brought in sponsor R. J. Reynolds and in 1975, introduced a new category called All American Grand Touring (AAGT). In 1977, the series would go through a series of major changes. IMSA permitted turbocharged cars for the first time as well as introducing a new category called GTX for cars based on the Group 5 rules. In 1981, after Bishop decided to not follow FIA's newly introduced Group C rules, so he introduced the GTP class for sports prototypes. In 1989, Bishop sold off his organization. After a period of decline in the early 1990s, the Worlds Sports car category was introduced in 1993 to replace the GTP category in 1994.

Sears Point

Sears Point is a prominent landform that juts into the San Pablo Bay in Sonoma County, California, USA. This hill is the southernmost peak of the Sonoma Mountains and forms the southwestern ridge above Tolay Lake. Starting with European settlement of this area in the mid-19th century considerable modification of the Napa Sonoma Marsh began to occur, such that in contemporary times, there is considerable upland between Sears Point and San Pablo Bay. Numerous local conservation organizations are presently working to restore hundreds of acres of these historic tidal wetlands as part of the Sears Point Wetlands and Watershed Restoration Project. The region can be accessed via State Route 37 or State Route 121.

Sears Point was named after Franklin Sears, who settled on 600 acres (2.4 km²) south of Sonoma in 1851. Later, he partnered with his father-in-law to purchase some 15,000 acres (61 km²), part of which is the present day racetrack, Sonoma Raceway.
