Auto Sport Quebec’s 2023 technical regulations have added an additional (optional) overall width specification for the Briggs & Stratton Junior, Senior and Masters classes. At the Coupe de Montréal we have been using the same specification for many years but we have issued a bulletin and corrected the series rules to specify that we are using the D specification as per the rules.
In practice, this bulletin does not bring any change for the drivers of these categories.
