1st autocross run.

So I signed up and ran as a guest in my first autocross event today. Found some things that need improving and would like some advice.

Quick rundown on my car. 70 duster, 360, reverse manual 727, 8 3/4 posi 3.55, HDK front w/ QA1 double adjustable shocks 500# springs, superstock 2800 springs w/ hotchkis/fox shocks, 1" lowering front spring mout, 275/40zr 18 rears, 245/40zr18 fronts, Goodyear asymetrical f1 tires. 13" cobra front brakes. 11.7" cobra rear brakes.

Had a little push, and a decent amount of roll in the front, the guys at the event suggested to get a bigger sway bar rather than messing w/ spring rates. Thoughts? Would using the adjustment in the shocks make much of adifference? The rear handled pretty well. But can see that the rear was moving side to side (could see marks from the spring touching the tti exhaust at the rear of the car). Anyone run or have advice on a pan hard bar? Any other input from personal experience would be great.

Like it was said, we need to know the wheel rates.

But 500 lbs springs seem a little soft for what you are trying to do. BUT can't say anything for sure without wheel rates.
