Cal trac /mono leaf results

my 2cents is with flyfish's opinion. it seems like you are over extending the rear shocks. a leaf spring car needs all the extention it can get. you only need 1" of compression for a leaf drag car, the rest needs to be extention. hooking up and then losing traction right away is a symptom of the body pulling the slicks off the track. also check to see if the spring perches welds arn't breaking or the perch isn't bending. sometimes they will need a gusset on the front and back. you also might consider putting the tubes back in. i'm not a fan of a snubber and don't see any reasong to use one for traction but it can be used for a safety device but keep it off the floor.
