I'm looking to do a few races this summer and see how I like it, and was wondering what I could do suspension wise to make the car handle better. My car is an '86, 3800sc, 4 speed muncie. I know tires are probably the number one item (a friend has been racing and been changing tires to find the best ones for his car) but what else?

Front and rear sway bars, lowering springs or coil overs

I agree. i autocross as well. If you have the extra money I have the Koni Special D adjustable shocks and love them. I have a front and rear sway bar as well. You can also do a polyurethane handling kit. Not suspension related but still handling related is a good set of summer tires.

I autocrossed my '84 duke for four years, and I'm now into my second year of using my '88 Formula.

So far we've mentioned tires (absolutely #1), front and rear sway bars, lowering springs or coil overs. I'll add that using cut springs to lower/stiffen the suspension is fine as well when done properly.

I'll also add that it's best IMO to try and stiffen the front a bit more than the back. To that end I've used poly bushings and Rodney's zero lash end links with the front sway bar. On the back I've retained the use of rubber bushings for the sway bar and end links.

And moving the battery up front also helps the balance and handling of a Fiero.

I like this camera angle of one of my runs last year. This was a more wide open layout than we normally have, which resulted in higher than usual speeds for an autocross event. I was going about 70 MPH when I entered the stop box.

Take off the steering damper when you run.

You are on a smooth surface and you will not get any kick back. The damper removed will lighten the steering response and effort.

Now on the road it dose help for kickback.
