I went ahead and did them on my T-100.It took a full 8-hrs to do the fabrication and install.
I'm presuming that they will assist the merging of the out flowing stream from the wheel well,with that flowing straight down the side.
If you've driven next to cars in the rain you may have noticed a jet of water-laiden air blasting transversely out the wells.This is what you're going after.
If you haven't seen basjoos AeroCivic,he has the ultimate solution.

I will just add that on the Honda Insight Gen 1, they included a very generous radius on the rear edge. They took a lot of effort aerodynamically, so I assume it helps a bit.
On the Insight they also scolloped the fender just behind the front wheel. That is imparactical for most DIY folks, but worth noting. Look at some Insight pictures on Autotrader and you will see what I mean.
I like the idea of smoothing in the front and top. That should minimize the amount of turbulence in the wheelwells.
In Hucho, the second best treatment of engine compartment air flow is to channel it out throught the front wheel well. It would require a lot of underneath sealing, probably with a good full car underbelly.
