Here is a quick run down of the POC GT classes. As Brad mentioned, they are basically a open class of prepared race cars that compete based primarily on weight to horsepower ratio and tire type.

GT Class / D.O.T. approved tires / Non-D.O.T. approved tires (Slicks)
GT1 / less than 6.51 lbs/HP / less than 7.01 lbs/HP
GT2 / 6.51 - 8.50 lbs/HP / 7.01 - 9.00 lbs/HP
GT3 / 8.51 - 11.00 lbs/HP / 9.01 -11.50 lbs/HP
GT4 / 11.01 - 13.50 lbs/HP / 11.51 - 14.00 lbs/HP
GT5 / 13.51 - 16.00 lbs/HP / 14.01 - 16.50 lbs/HP
GT6 / >16.00 lbs/HP / >16.50 lbs/HP

More details can be found on the POC website.

A base 2.5 Boxster Spec would typically run in GT-5. I was pleased that I was able to chase down, catch, and pass ANY GT-4 car.
