Good thread and I'll keep this in mind when I finish Auto-X and move up to road racing, but:

Not always. The rear-end actually wants to swing around and induce oversteer while entering corners. Balancing the throttle with this oversteer actually keeps the car in line and even helps you corner just a little faster, which makes splitters and spoilers unnecessary at up to some 60 MPH. Also, I'm sure you agree that the Yaris can't reached speeds past that range due to the fact 1) it's painfully underpowered (unless you own the 300HP Garmobile) and 2) not all tracks can give you a long enough straight-away to reach speeds that can effectively induce downforce up to the next corner. 2¢.

Hmmm, my Yaris understeers but I think it's because of all the suspension work. I guess the only way to get your Yaris going fast enough is if you can get the handling down so you minimize the speed loss in the turns. But I agree with you.... for all practical applications, the Yaris doesn't need a wing. That's pretty much my point. But I've done a lot of aero work so I figure I could talk about it if anyone cared to listen.
