All this discussion has got me thinking about my setup. I have Cal-tracs with mono leaf springs, bottom hole, ¾ turn pre load on right and about ¼ on left. Best 60 on a good track 1.403. On an average track is 1.44 to 1.46. Poor track it spins. I going out to move the bar to top hole for tonight’s T&T just to see what the top hole will do. The track usually is average to poor on Friday night. My car weighs 2840 with me and 8 gallons of fuel in it.
