CHD 2.1 MODIFIED CLUB CLASS RULES 2016/2017 (Version: Web1)

Please note that only the exceptions from the rules according to MSA are noted.

If not mentioned the MSA rules will be applicable.

In interpreting regulations and specifications “what is not specifically permitted is disallowed”. You may only do something if the rules say you may.

Visiting drivers – race within CHD rules for points & trophy if the car adhere to the club rules.

CHD club drivers will be re-scored after the event to exclude the visiting drivers from the club points. E.g. Visiting driver won race 1 and CHD driver was 2nd. With the re-scoring the CHD driver that came 2nd will be re-scored to 1st.


There is a vast difference between being found to have contravened technical regulations and deliberately planning to be outside the regulations and taking premeditated steps to disguise these irregularities. A good example of cheating is where an electronic control unit on a vehicle is opened and altered internally, contrary to regulations or where another control unit is wired into the harness and hidden.

Where technical consultants believe that the line between being illegal and cheating has been crossed, they shall report this to the race officials, having excluded the competitor from the results. A competitor found guilty of cheating shall be banned from racing for 6 months without the option of having the ban suspended.

At least 6 cars are required at event to qualify for club championship points, however should not more than 40% of the events in the season have less than 6 cars entered, those events will still count as long as there is an average entry of at least 6 cars throughout the season.

In the event that this does not occur, the event with the fewest entries will be removed from the seasons scoring, and the average entries recalculated to try and obtain the average of more than 6 entries for season.

Should there still be an average of less than six cars for the season the class will not qualify for club championships status.


The committee or the technical rep are responsible for pulling of cars for checking – no driver can protest against another driver’s car.
