This is the smalles capacity modified engine class, ideal for those who want to squeeze more power than anyone else from a small engine.
This class is often used as a 'stepping stone' from Class One into the larger, more powerful classes as you can - with relative ease - convert a Class One into a Class Four.
The car used must be a front or rear wheel drive saloon; hatchback or pickup.
The engine must be of a maximum 1130cc capacity, be of the type originally fitted to the car and must remain in its original position. There are unlimited tuning modifications allowed.
This is a popular class and consists of mainly classic Minis with a few Imps and Fiats, however the class is now expanding with many different models of car entering the class.
