Although last year I had an enlightening experience. My 1991 Civic Si was setup to oversteer. Which is pretty normal for most autocross cars. THe problem is I was getting deathly afraid of it. Ran into one of my buddies who was running the Northeast Divisionals in grid with me last year.

Told me I would drive the car faster and harder if I was comfortable with the car. So I dialed out some of the oversteer by softening the rear shocks. And WOW what a difference it made for me. I was about 1-2 seconds faster on that course. And I believe I won by 1 second the first day.

I remember my CRX being tail happy just in the snow when I had one. I was told to add weight to the rear since the car is very light back there. For autocross of course you do not want to do that.

So you can add performance shocks like Koni Yellows and turn up the front shocks to full stiff that should limit the oversteer. Also you can change tire pressures so that the front and rear tires have the same air pressures. The more biased you make the pressures the more it will oversteer. I would try like 45 front 44 rear (street tires). If you go 45 front 35 rear the car will snap oversteer.

Also check the alignment and make sure you are running like 0 toe front and maybe 1/8-1/16th toe IN. Toe in will settle a tail happy car.
