My car's a 72 tii with Bilstein Sports, stock (or really old, can't tell) springs, and the standard 22/19mm anti-sway setup. Tires are AVS Intermediates, 195/60x14 all around.

I have my rear swaybar set in the middle, too. Since it's not something you can change in-between runs, I leave it there.

But since you can adjust tire pressure easily between runs, I start with my tires at 37 in the front 35 rear. If I start to lose the rear end (usually happens when it starts to get hot), then I lessen the rear tire pressure by 1 pound, and that gets it back in line. Like this, the car is very neutral and compliant.

I personally find that you can do quite a bit of fine-tuning just using tire pressures.

In general, racing a 2002, you'll be up against cars that are less nimble, probably with more traction, and more power. To optimize the differences, I set up as early as possible for turns and keep as much speed as possible throughout. Always be right on setting up for slaloms as well, that's one area a mildly suspension-tuned 02 can really make up time against heavier cars.

Good luck!

PS. One other thing - remember you can adjust the swaybar one side at a time, so if you have three holes on either side, that's really 6 total settings. A swaybar doesn't know right from left at all...AJC

You can REALLY get your understeer/oversteer to the point you want by adjusting tire pressures, specifically as Andy mentioned. Decreasing rear tire pressure tends to increase understeer/decrease oversteer. Be careful, however, when mucking with front tire pressures if you run negative camber because too much pressure can adversely affect the intended effect of camber adjustment.
