Yes and no.
An ideal spoiler should generate downforce. At the same time it should reduce the drag coefficient by optimizing the airstream. So if it is designed well it should not make the car slower but generate downforce.
Other aspects: front and a rear axle have in general different down- and upforces. So you have to optimize the whole body system aerodynamicly.
But if you can drive only 55, i think there is no need for big aerodynamic experiments.

279 - that's the number i get in my instrument cluster on the flat Autobahn.
