How do I get my bonnet like this?

(Pic shamelessly "borrowed" from another forum)

 

I presume its just a few spacers, is that right?

Because the had a wind tunnel, and like every manufacturer going they know that the area below the screen is a high pressure area, hence all heater units get their air from there, raising the rear of the bonnet will allow air to escape when stationary (the fan pulling air in, and heat rises so escapes out the top/gap), but as soon as you start moving the high pressure stops any air comming out.

Same as lourves, the upper surface of all bonnets has whats called the 'Boundary layer' which is an area close to the bodyshell which has no air movement, most noticible on bonnets when its rained.. you drive away, and the water stays on the bonnet till you brake, then it falls off the front edge.

This can also show on some cars how much return airflow there is from the screen, you can watch the water droplets acctually creep down the bonnet toward the front as your speed increases.

Ever noticed those little sprays of rain water come up from the front edge as your drive along?
