First Day at the track

I did have a front sway bar. I pulled it before I went to the track. The pinion angle is correct. The rear shocks are set on #1 the lightest setting. I tried hazeing the tires to just clean them off & tryed heating them up. The track starter said they just scraped the tracked, but most others were still hooking fine. How critical is the front suspension height ? What if the clamps on S.S. springs are pretty snug to tight ?
