I was, and will be running again, the same style of cooler located in the lower opening I didn't want to interfere with air flows at all to this small cooler.
So a made a rego plate holder that sat the plate at an angle in front of the base of the radiator within the larger nose opening. I angled it to lessen the air dam effect but to still retain some visibility.
My thinking was that the radiator was so much larger, that there would be less impact. In fact I think the car ran cool for the short period it was operable anyway and I didn't have any issues in this regard.
I'd love to have a spring loaded version hanging from the top of the opening that swings back and upwards with forward car movement for no air impact and low photographic opportunity but it wont happen.
See the pic below for what I had and will return to.
Cheers
