Default Toe out in rear to reduce push?

Our Miata rarely pushed but once when I installed a very soft rear bar it did push so I dialed in some toe out in the rear. The toe out made high speed braking something to fear as it got very squirely but it sure improved rotation. Needless to say I quickly replaced the soft bar and went back to slight rear toe in. How does the WRX respond to rear toe out?

It responds very well to toe out.

Last season:
Front: 0 toe (per side)
Rear: 1/16" out (per side)

Hindsight being 20/20, I feel this was too conservative.

Next season (to start with):
Front: 1/16" out (per side)
Rear: 1/8" out (per side)

I'll probably adjust during the season, but this seems to be a good initial value (for Koni SAs, 24mm adjustable front sway, 225 Kumho).

Apparently Larry Fine was up to 1/4" toe out in the rear (per side)!!!!

Obviously a VERY aggressive alignment should be for autocross use only. Don't drive with extreme toe out on the street, or you might kill yourself.

If you plan on running in SCCA Stock class, rear toe out is the ONLY way to get the car to rotate, especially on grippy R-compound tires.

I recommend at LEAST 1/4" for autocrossing in concrete and 0 to 3/8" on tarmac.

I run 0.10 degrees toe out front and 0.05 degrees toe out rear, all the time. I have no idea what this equates to in inches...it's probably very small though.
The car pushed just a tad too much with just camber adjustment so I used toe to liven up the handling a bit. When I did it I had no idea how it would turn out, so I decided to be conservative on the toe values. Absolutely zero tire wear issues.

With those alignment settings do you guys trailer your cars to events?

I personally found 1/16 was the perfect balance, and 1/8 toe out made it "too loose" but it also depends on your suspension and tire choice.

I used to do the rear toe when I got to the event. Its very easy. Just mark what stock is, and then CRANK it all the way. If its too loose. Crank it back a bit

I ended up running about 1/4" toe out in the rear during the season. For the last event of the year (after nationals dammit) I tried running almost 1/2" per side (as much as you can get) and LOVED the way the car felt.

Might even be able to get away with a 26mm front bar with that toe out.

I ran 1/8" total all the way around and I'm going to experiment with more this year with the addition of a front sway.

I've run anywhere from 1/8-inch to 1/2-inch total toe-out in the rear this year. Very much course dependent. Like Tom said, I just change mine at the events.
