Hey guys, thanks for all your nice comments! Thanks Brian B for your comments on YouTube too, I didn't realize you were also on here
I replied to your comment on YouTube with more info on my setup. The app I mentioned, TrackAddict is absolutely amazing and fun to mess with, even if you're not racing, and its FREE! Any car guy should play with it, seriously. The free version of RaceRender is also awesome. The free version is limited to 3 min videos, so it was fine for autocross, but I upgraded so I could make the canyon run video, and I like supporting companies that do good work when I use their products
j-dub: As far as I know, you should never have toe-out on a swing axle car! Those cars are dangerously and often unpredictably tail happy to start with, and having toe out in the rear will make it worse when the car is pushed. Rear toe out makes the rear of the car try to steer the car!
The proper amount of rear toe is tricky and probably somewhat controversial. How much power the car makes can influence it, the type of spring plate bushings (soft rubber vs. urethane vs. solid metal) can all make a difference. Under power, since the rear of the car is pushing the car, rear tow-in will increase. The more power, the more the increase, and the softer the spring plate bushings, the more toe-in will increase. A lot of guys seem to set it at close to 0, knowing that then under power they will get a little toe in. That should be a safe way to do it.
The rear of my car is a mess right now and I've been neglecting it. I have a stupid amount of rear toe-in, like over 1/2"
Why, I don't know, I never measured it till recently.
Pretty sure I will have to lengthen the slots on the spring plates to change it to a reasonable amount. That much toe gives you tons of rear traction, but at the expense of a lot of rolling-resistance, which only serves to eat horsepower and wear tires. I think I am going to address this next on my car.
