- Increase area template requirement (something like 170K mm^2)
- Cooling outlet outer template 900mm long, with the final 325mm allowed to intersect the rear suspension templates
- Drivetrain template split into 2 templates instead of 3 - engine template and gearbox template (no upper/lower engine template)
- Abandon the 'shrouding' rule on the outer templates for the inlets. Use the subjective wording in K4.1 and K4.3 to govern unrealistic designs which would otherwise be legal. If this becomes a big problem then we could think about re-introducing this rule, or something similar.
- The 'realistic volumes' between the cooling inlet and outlet, and between the engine inlet and the engine: use 'offset' guides in the guide file to indicate how much space should be left between the bodywork and the corresponding internal template, where neccesary, to remove some of the subjective interpretation. Would not apply to cases where the internal flow would not pass by these templates (for example, where the inlets and outlets are both in the 'sidepod' area of the car).
