the rules were brought in by EFRA, we decided to follow and added them to the brca rules, the thinking was that if we kept what we had then we could cause problems for our drivers attending EFRA events, having a shell that was allowed at our nationals and then the driver having to change shells at the euro's. or worse turning up at the event and having your shell disqualified along with your score!!.
i am not 100% sure on why efra decided on the scope and size of holes, but i believe that the old rules which said you could only make openings if they were marked by the shell manufacturer led to some shells appearing with a multitude of marked areas. it could of led to the situation of a buggy shell being nothing more than a skeleton atop a chassis.
the rules are confusing and i find it difficult myself to work out exactly what is or isn't allowed but they were written so all of the efra block could understand them!. i think the term "lost in translation" comes to mind.
