These are vehicles with a steel tube space frame chassis, either home constructed or professionally built, divided into three classes by the application of an engine capacity and/or engine type limit.

The specials are strongly built to withstand a collision or roll over, but are not fitted with bumper bars as deliberate contact is definitely not allowed.

There are unlimited tuning modifications allowed, the engine / gearbox / transaxle / axle types are free according to each class cc limit and specification. Specials are fitted with a multitude of engine types with 1.0, 1. 1, 1.3 Motorcycle, 1.3 / 1.4 SOHC & DOHC engines or 1.8, 2.0 SOHC & DOHC engines or 2.1, 2.5 DOHC / 2.8, 3.0 V6 / 3.5, 4.0 & 5.Oltr V8 engines, mainly being mid or rear mounted to a Hewland / Renault VW gearbox or direct drive.

All of the special classes are very popular with the spectators. Many are geared to achieve speeds of 100 Mph!
