It began on February 3, 1990, and ended November 11, 1990, after twenty rounds.

Drivers Championships

Geoff Brabham's Nissan NPT-90 at the 1990 Grand Prix of Greater San Diego

Geoff Brabham won the GTP Drivers Championship driving a Nissan GTP ZX-T and a Nissan NPT-90.

Manufacturers championships

A championship for manufacturers was awarded to each of the four classes. For the prototype classes, only the manufacturer of the engine was used rather than the manufacturer of the chassis.

Points were awarded to the top 10 on the scale of 20-15-12-10-8-6-4-3-2-1, with exception for the 12 Hours of Sebring, which added five points to each position on the scale, and the 24 Hours of Daytona, which added eight points.

Only the highest-ranking entry from a manufacturer was awarded points at each event. Any other finishes by that manufacturer were merely skipped.
