Group ND Proposal
The radiator may be replaced but must retain its original location, form and function.
The support panel opening may not be modified except for mounting bolt locations.
The material from which the radiator may be manufactured is free.
Any attached fans or shrouds are free
The control system for any electric fan is free
Justification and Rationale
Allows commonly seen alloy radiators and electric fans to be easily added without disagreements
Freedom with electric fan controllers will allow competitors to choose to use off-the-shelf simple controls or make it a function of either factory or aftermarket ECU
