Yeah, it's because this topic was linked in the intake manifold thread that Ted brought back from the dead.

Once you put on a real rear wing, it's very easy to get too much downforce in the rear. Removing the valence actually makes the wing's adjustment range more usable.

Then that shows exactly how effective the rear valence really is. I would think it would be more efficient to run with the valence, and a less effective wing, instead of a more effective wing, and no valence. Reason being, a wing creates more drag then the rear valence in proportion to how much downforce they create.
