The first time I drove the car was at an out of town race with a really loose track. I used Tony's base set up and it was all over the place. I lowered the shock oil to make it hook up better, shortened the wheelbase (makes a huge difference for me) and running a long camber link (inside hole, 2nd from bottom on tower and upper outside hole on hub carrier). The front is the same as base set up other than running 3 hole in the ackerman. O, i also put 21* caster...
Hope this helps. I used to run 7/5/1 in my R to get more "pull" instead of "push" and it worked well. I might try it in my sx8 and see what it does. If your on a loose track, try running the short wheelbase. I put it back to the middle and it was loose. Changed it back to short and couldn't believe how much it changed the car. That little 1mm clip mad all the difference in the world. IMO. So 1 change can do a lot.
