I can't seem to get my car to quit spinning at the track, and I am looking into a set of Cal-tracs or the Competion Engineering slide-a-links. So what are the pros/cons to each? Which work BEST with SS springs? And last (but I'm sure I'll have more questions) what are shocks work well with this type of set up? I currently have SS springs in the stock location with a C-body shock on the car now. Best e.t. of 8.21 with a 1.9 60ft, all in a 73 Swinger with a mild 440/727 with 3.55's and a 2800 stall, and Mickey Thompson E.T. Streets 235-60-15's. I know that more gear will help alot, and I have a set of 4:10's that should help the e.t. but I want to get the spinning under control first.
