S13 Autocross Coilover Setup

Always more camber. Not drift-tard levels like 6*, but 3* will make it better.

More camber will allow you to drop pressure, too. You can read the edge of the tire and adjust pressures accordingly.

Also, square tire setup helps, and a bigger front bar.

Obviously tire compound is paramount for autox, so better tires will help immensely.

Thanks for the pointers. I'll add a couple degrees in before the next event. My tire's only have a max pressure, so I'm not sure how low I should take them. I had them at 30 all around.

A front sway bar is a good idea. The nose is really diving in the pictures that were taken. What would be a good size to go with. I found this thread which outlines sway bar options. I would guess you have to match it to your spring rate, so lower spring rates larger bar dia?

Stiffer front springs are in order, I would say start with 8k. You can drill another set of adjustment holes in the front sway bar to make it stiffer. I used to run the SE 25mm front sway bar with stiffer adjustment holes drilled about 3/4" in front of the stock endlink mounting points. As for your rear bar, GET RID OF IT. The HICAS 21mm rear bar is way too stiff. With that bar combined with your soft front springs I bet the car is VERY loose on the throttle. I used to run without a rear swaybar at all and the rear grip on the throttle was MUCH improved.
