Thanks.

The only thing I'd like to mention, refers to a ' SHOWDOWN FOR SPOILERS', which was published long ago, in CAR LIFE Magazine, June, 1969.
A flip-up rear spoiler was fitted to a Chevrolet Camaro Z/ 28, and tested in an un-disclosed stretch of highway near the California / Nevada state line, USA.
At 115-mph, the spoiler created a pitching moment, lifting the nose with 400-pounds ( 180-kg ) force, while providing 125- pounds ( 56.5-kg ) rear downforce.

Obviously something wrong with those figures, isn't there? You don't get a greater force on the other end of a lever when the fulcrum is near you. I'd imagine that they were the total front and rear figures, not the front lift caused by the rear spoiler, as you imply.
