Sorry, but had to jump in.

I understand why is Efrain asking ( guys rather see rules that say what can't be done, but then the book would be endless and full of loopholes)

Anyway.
Most of us have o problem with English (written or spoken) and we are not new to racing or rules ( the Club itself is 40 years old) first Grand Prix in Puerto Rico was in 1962, and we have been thru many rule books.

The main problem is that people build cars without reading the rules, or asking the tech inspectors (we just sent notice to all car drivers and whomever might be building a new car for IT or GT, to feel free to let us know and the tech inspectors will meet them and explain the rules clearly)

Then again I strongly believe we have to adapt to our reality, the cars we have available, and what people are willing to race with..
The era of the Trans Am/GTS, GTU and RS (IMSA) racing all over the Caribbean,Central America and South America are long gone..
