This class is designed for naturally aspirated vehicles using OEM equipped or swapped OEM engines 2.5 liters and under, and common modifications to popular trackday vehicles are largely permitted, in rules below. OEM forced induction vehicles of 1.6L and under are also allowed when using completely stock turbo systems.
● Forced induction cannot be swapped INTO any vehicle.
