EVOlutionary's Autocross Rules
Corey Ridgick at one of our local events: he has the wheel already turned for the next cone before he crosses the centerline of the slalom.

A closeup, where you can see he's actually steering inside of the cone:

...and just to prove he didn't cream the cone:

I have datalogs from Atlanta that show me turning in just slightly before my car owner in one corner. I gained almost a second by opening up the turn. Over-doing late apexes doesn't pay off in autocross because there's no straight to carry extra speed through.
Nice pic GT. That clearly demonstrates that all drivers are not created equal. Not because he is doing that, but because he knows when to do it. Some guys will dive bomb apex's straight on to try to do the little hook move your showing and end up.. well end up hehe.....
For slaloms trying to hit the lead cone with the rear inside tire is a natural usage of this technique.

Sometimes I'll do it, and sometimes I won't. I know some very fast people that that's all they do. A lot of ex-flat-trackers get Superbike or even MGP rides because they get around the track very fast by squaring the corners off. A lot of car dirt-trackers get rides in Indycar, and even NASCRAP with that style as well.
It's one of those things where two guys from two different backgrounds could butt heads all day about it, and then go out and prove their both right with fast lap times. Another reason for the "Ahhhhh Jeeeeeeeeezze"
After doing some real racing a few weeks ago (sort of) I realized how different road racing and autocross really are. In road racing you're driving the car as quickly as you can while keeping it stable and in control. In autocross, you're trying to keep the car upset and just on the edge of control. I know an autocross run went really well when I felt the back of the car moving in nearly every turn. Moving the steering wheel early gets the car to rotate, and allows you to set up for the next turn early, which keeps you moving faster. It also reduces the distance you cover, which is absolutely critical.

I would say it feels more like "surfing" the course. Slithering describes it pretty well too.
Actually, the more I think about it, it feels a little like waterskiing. There's kind of a turn-slide-stick, turn-slide-stick rhythm to it.

This is kind of an extreme example, IMO, but being loose in some places can also be the fastest way around a road course too.
Kinda my whole point. There's not only one way to go fast around the track. You need to have a lot of tools, and have the chest open, ready to use 'em
Great Post!!
I've never been to an Evolution School, but that statement sums up what I've been feeling. I'm a noob to autox just for reference. If I've had a run that just stuck I know it's too slow and my times typically proof that.
Now how do you slither the car around those cones when you consistently actually run over them with the back wheel/half of the car?

-As Griceiv said, stiffer rear bar
-Higher rear spring rates than front
-Stiffer rear shock damping
-Run 2-4psi higher in the rear tires
Beware- doing ALL of these things together can make the car REALLY loose in back! Especially with cold tires, you may be surprised just how loose. Don't use them on the street!
Having a car this loose means you need to be very smooth, and you will benefit from the early steering (and other) inputs mentioned before.
