Forget about larger or smaller volumes, does it fill out the template or not!!!!

On my S10 the rear spoiler works because it fills out the template. You can be a little higher or a little lower, point is to get as close as possible. The Bonneville racers tend to go in the horizontal direction in lieu of my 45 degree spoiler but the concept is similar - fill out the bloody template mate.

The 10-degree surface rule is a safe bet for air attachment.

Some conditions warrant greater or lesser angles, again it all goes back to the Aero-Template.

May the template guide you in your journey.

EDIT-2:

My rear spoiler used to be adjustable - I forgot about that, it rusted to it's current angle years ago.
