if i wanted to do auto-x what suspension parts would it be best to put on my car?

 

tires/shocks/springs/swaybar/rollbar or front and rear strut bar

optional things: pillowball tops/ camber kits/ new bushings.

I'm taking a shot in the dark cuz i don't autocross, but seems like it makes sence. Those are the things i put on my car so far.
