Class Structures

Since the formation of the RSA we have always tried to keep our class structure simplified — in the early days we started with six classes and found this suited our pool of original competitors. Over the last 16 years car performance has changed considerably and to maintain a fair class structure we have made some relatively minor modifications to class organisation to move forward with the current times.

Our research has identified a class structure commonly used throughout the UK in MSUK regulated events at similar venues, and we believe it to be a suitable basis for the RSA going forward.
