Group ND Proposal
The transmission, clutch, flywheel and any mountings are free save that:
- Any replacement transmission is from a production MODEL, but ratio changes are OK provided the gears retain a helical tooth pattern.
- The transmission retains the same number of forward gear ratios as the model.
- It retains a H pattern manual shifter located in the MODEL location and trimmed/finished as per MODEL
- Dog engagement of gears (non syncro) is not permitted.
- No form of automation of the shifter system or clutch operation is permitted.
Any changes to the bodywork to accommodate a replacement transmission must be neatly finished so the interior appearance is unchanged.
Justification and Rationale
These freedoms will collectively maintain the lowest possible cost of competition by preventing race-only dog boxes and/or sequential shifters being adopted.
Insisting on an unchanged interior appearance helps to maintain a PERIOD appearance whilst still allowing for transmission changes.
