Class Structures

CLASS STRUCTURES

Since the formation of the RSA we have always tried to keep our class structure simplified as in the ‘early days’ we started with six classes and we found this suited our ‘pool’ of original competitors and it has worked pretty well over the years.  Over the last 16 years car performance has changed considerably and to maintain a fair class structure within the RSA in the future we feel that some relatively minor modifications to class organisation are  necessary to move forward with the current times.

Our research has discovered a basis for a class structure that we believe to be suitable for us which is commonly used throughout the UK in MSA regulated events at similar venues and events that are very similar to the RSA formula.
