cal tracks vs slapper bars

I am sure that some of us older guys have had good luck with slapper bars, i ran a pr on my 64 fury 426 wedge. but that was back in 1968 or so , granted it took a little work to get them to hook. i guess the question i am asking is this, are the cal tracks better on the street or at the track? and what is the advantage over the old style traction bars?. and why do they only work on certian spring combos, and not the others..... this doesnt make sense....

IMHO, slapper bars never really worked very well on MOPARs. I have a '69 Charger R/T and ran a set of Lakewood traction bars for a while many years ago, but I ended up getting rid of them and went to Super Stock springs and a pinion snubber with much better results. The traction bars caused wheel hop and didn't really help increase traction at all. I'm getting ready to install a set of Caltracs on my '69 Dart using my stock V8 leaf springs that will be driven on the street and at the track. The Caltrac bars help to stiffen the front spring segment instead of bending it as traction bars would do, thus increasing traction. Check out Calvert's Web site (http://www.calvertracing.com/info/info.htm) for more info on the concept. The write-up is very good and makes sense. Besides, Caltracs are run on a lot of fast MOPARs and they really work well.
