Bonneville Landspeed Racing - Let's Try a Thing.

Ya shutters. That's how modern cars work. If the cooling system does not need the air they shutter the radiator so more of the air goes around the car instead of through it. They are also smoothing up the undersides. Eliminating things like rocker pinch welds.
As this nose gets worked on, it will have more ground clearance. The height I used was just due to blocks I had readily available. I need a good way to support it. Looking at ways to make bolt on mounts from the bumper bracket. The radiator ducting will be reduced in size - especially for race times. Shutter is an interesting idea, I will keep that in mind.
