Class Rules

*NEW* Fast Road versus Open Class as of the 2013 Season

The committee has introduced a new system to help sort cars into the Fast Road and Open classes. The explanatory statement can be found here, and the excel spreadsheet here.

Version: 2012

The MG Road Racing Championship is open to all cars of the MG marque. All competing cars must hold and conform to a current CAMS log book. MG Racers are encouraged to endeavour to have their cars comply with either the current Sports Car (2nd category) or Historic (5th category) rules as contained in the CAMS Manual of Motor Sport. This will ensure that the owners can run their cars in races other than MG. Please feel free to contact a member of the MG Racing Committee for assistance at any time.

Decisions regarding the categorisation of cars are made by the MG Racing Committee at its sole discretion.

The Committee reserves the right to nominate the appropriate Class (see below) in which each competitor accumulates points for the MG Road Racing Championship.

The Scoring System for 2012 will remain unchanged, refer here for the scoring system.

To be eligible for outright points a competitor must be a member of any MG Car Club.

Outright points can not be aggregated if a driver changes class with the same vehicle.

A competitor who uses two or more cars in different classes can not aggregate outright points.

A competitor who uses two or more cars in the same class can aggregate outright points.

For the purposes of the MG Road Racing Championship, competing cars will be classified as belonging to one of the following Classes: 

  • Open Class: Class 'A'
    • This Class caters for MGs that have undergone significant development work and which are neither Historic nor Fast Road (as defined above). To comply, cars must be based on an MG chassis/body and an MG vehicle production engine (see Note 1 below).
    • Purpose built race cars shall be categorised as open class. Therefore all MGF Cup Cars will run in Open Class

    • Open-2: Over 4 cylinders, and including turbo or super charged 4 cylinders.

 

  • Fast Road Class: Class 'B'

    • Competitors in this class do not qualify for Outright MG Road Racing Championship points but only accumulate points within this class.
    • To reiterate entry into this class is by invitation only. Competitors wishing to compete within this class are asked to apply to the Racing Register Committee for consideration to be included. If accepted, an invitation will be extended to that competitor to participate in the season.
