alignment for autocrossing

I posted a while ago about what suspension I wanted to get for autocrossing. after reading some rules and talking to different people that race right now I decided to just try and get adjustable shocks.

The same guys said there is alot I can do with my alignment. He said the car needs camber and toe to realy make it handle right.

First, does this sound right and second what exactly is it going to do?  

making your camber negative makes the tops of the tires closer like this /_/  \_\.. I can't really think of a good definition for how this helps but it does definatley.. my merkur has the suspension alighned like this .. its hell on the tires but works awsome..
positive camber is when the boittom of the tires are closer together like this \_\ /_/.
I don't really know when this is used .. acutally I think some rock crawlers have there trucks sett like this.  wait stop I just found a good site to explain this to you.. http://www.ozebiz.com.au/racetech/theory/align.html

Also for racing you are gunna negative camber.. I dunno to much about toe I forgot that semesster in school.. it was a blurr  

like SAV said, you are going to want some amount of negative camber in your setup. Basically you want to keep your tires flat with the road, as your car rolls/leans your tires lean with it and you end up diriving on the sidewall of the tire. With negative camber when your car rolls, the outside tire will actually roll over to be flat on the road increasing the contact patch. Obviously when the car is at zero roll you will have less tire on the ground the more negative camber you have, so you are trading straight line grip for cornering grip. Extreme camber angles aren't really suited for street driving either. They will make your car wander more, plus it makes your tires wear significantly faster since you are driving on just the insides.

Toe is when you are looking down at the front wheels and they are either pointed towards or away from each other. Toe-in(the front of the two tires are closer together) makes the car more stable. Small steering inputs don't effect the car that much because you have to turn the wheel more to get the tire pointed outside of the cars natural path. Toe-Out can be great for autocrossing, the car turns in much faster since it basically always wants to turn with toe-out. It is also nice because with toe-out your inside tire is turned more sharply than the outside. When you take a turn the inside tire has to follow a smaller arc than the outside. The problem again is that extreme settings are very tough on tires and make your car less stable on the street. If you have ever driven a car with a couple degrees of toe-out on the freeway you will know what I'm talking about. You are constantly steering to keep the thing in your lane.

For autocrossing you may want to see if you can dial in maybe two degrees of neg. camber. It shouldn't be too bad on tires and should give you the bite you need to get in and out of corners. I would probably run 0 toe. At most I would run maybe an eighth of an inch of toe-out any more than that and it will be a scary ride for daily driving.  

what he said..^^^^^^^

TIVE!  

does anyone have any experience fooling with other than stock sway bar diameters ? I have a 07 si and am interested in [some] oversteer.  thicker rear bar?
