66Valiant528, My Son and I switch out 3 things in my rear suspension since last September and we are still adjusting to get a handle on it. The first thing we changed were the front halves of the Cal-Trac leaf springs. ( after to many years of 5000 rpm clutch drops, they folded over and arched the opposite way) Then we switched out the rear shocks for D.A. Vikings from the 5 way adjustable Ranchos that came with my Cal-Tracs 20 years ago. So my Son and I decided that since we made those changes we might as well put sliders on the rear of the springs too. The shocks on Sunday were set to 9 clicks rebound, 4 clicks compression on back and front QA1 were set to zero . The Dart always hit the tires hard but now it is crushing the side walls and then compresses and rebounds and tried to run over the tires, then as it climbs up on the tires the front end comes up and down the track it goes and still managed a 1.502 60' on a so/so track. Next timeout we are going to try 1 or 2 clicks more on the compression and/or 1 or 2 more pounds of air in the stiff sidewall 9-28 M/T slicks. If that does not control the hit we will try lowering the two step RPM and/or dropping the bar on the Cal-Tracs from the top to the bottom hole on the front spring eye to soften the hit.
