The GGC autocross system has been created as a method to classify & equalize BMW and Mini brand automobiles. It uses a formula to calculate base points which takes into account horsepower, torque, gear ratios, differential ratios, and weight. On top of the base points we add points for wheel widths, suspension stiffness, and owner-added modifications.
To equalize a time, use the following formula: equalizedTime = ((60/59.901) ^points) * actualTime * 0.85
The system has been primarily developed by Matt Visser, Jason Sams, Jeff Roberts, Kris Linquist, and Ryan Rich.
The system is revised periodically by the Autocross Team. As revisions are made, they will be noted in the list below.

|March 22nd, 2017||A car was added the to system: 2001-2006 M3 (Without Sunroof). This car has 55 base points.|
|March 22nd, 2017||The description for camber modifications have been updated to include the removing of alignment pins to achieve more camber.|
|March 22nd, 2017||Added the "W" class, where everyone is a winner!|
The point to class table can be found below.
|Gonzo||80||998||Y||((60/59.901) ^points) * time * 0.85|
|W||999||999||Y||(((60/59.901) ^points) * time * 0.85) * 0.000|
