Championship standings

Points systems

Championship points are awarded in each class at the finish of each event. Points are awarded based on finishing positions in the race as shown in the chart below.

Drivers points

Points are awarded in each class at the finish of each event.

Team points

Team points are calculated in exactly the same way as driver points, using the point distribution chart. Each car entered is considered its own "team" regardless if it is a single entry or part of a two-car team.

Manufacturer points

There are also a number of manufacturer championships which utilize the same season-long point distribution chart. The manufacturer championships recognized by IMSA are as follows:

Grand Sport (GS): Car manufacturer

Touring Car (TCR): Car manufacturer

Each manufacturer receives finishing points for its highest finishing car in each class. The positions of subsequent finishing cars from the same manufacturer are not taken into consideration, and all other manufacturers move up in the order.

Example: Manufacturer A finishes 1st and 2nd at an event, and Manufacturer B finishes 3rd. Manufacturer A receives 35 first-place points while Manufacturer B would earn 32 second-place points.
