How to make this Dart Handle?

Everyone's prefrences are different. I run a bench seat and manual steering (but my seat is now modified). As far as the car goes, you can go to my website's tech page and see what I've done to make it a better autocrosser.

The cheap and easy places to start on the car are the t-bars, and sway bar bushings. For driving, you're going to have to snug those belts up and plant your left foot in the corner. But if that was your first autocross, then you did fine. It takes a while to learn the game and to finese the car.

Another big difference is tires. There can be 2 to 4 seconds just in tires, even more if the tire and conditions are not a good match. I'm still running my 10 year old Toyo RA1s (225/50r15) which is a moderately good r-comp, decent in the wet and holds up well. Hardly the best autocross tire, but a lot stickier and more fun than my street tires. A good compromise for doing well while lasting a reasonably long time.
